I recently took a figure structure class on Proko, and the instructor talked about the use of S-curves and C-curves in gesture and movement. The idea gave me quite a few insights. It felt very similar to the way I think about sketching with gesture lines. I tried applying the construction methods from the class to different poses, to see whether the same underlying drawing logic could reveal common patterns across a variety of movements.

Hi, I'm Lynn. I started drawing 2 years ago by following random drawing tutorials on YouTube. I discovered Proko.com on YouTube while looking for a hand drawing tutorial. I want to be able to draw anything I see. Any recommendations??

I looked around proko.com however I could not find any image pack of skulls from really all angles. Is there any place where I can find ? An accurate 3d ct scan would be good too.

The hardest part of these for me is when I try to imagine how the forearm muscles actually insert and wrap based on pronation or supination, it doesn't always look on the surface like the anatomical models I study. Anyone else try this sort of thing? This is from self-directed work through books (Winslow, Hampton, Lauricella) but I will get to the arms in the Anatomy course eventually & see what tips they have there.

Here’s a portrait study of a woman wearing a hat. Thinking about it, I’ve probably only drawn elderly women a handful of times. The hollows created by sagging facial fat in older faces turned out to be especially interesting to draw.

I’m quite new to this platform. Being somewhat of a beginner artist, I know that my sketches aren’t as professional compared to other Proko Users. Tending to make multiple mistakes with anatomy. Beginning of April, I focused on the muscles/bones of the arms. The first day is shown on the left. The most recent is on the right. I still want to know what I need to improve on or if I’m making any progress at all.

Sorry, my English isn't very good. I used translation software.I've been working on my back muscles lately.

I drew several different expressions. Compared to the previous study, I added more side-view angles and subtle muscle variations. The wrinkles created by muscle contraction and relaxation add another layer of emotional tension to the expressions. It also reminded me of Our Little Sister, which I watched yesterday. In many scenes, the subtle changes in Haruka Ayase’s expressions convey emotions that were never spoken out loud.

I drew portraits from several different angles, trying to break down how the shifts of light and shadow on the face are formed. While drawing, I focused on building the volume, thinking of it as constructing the transitions between planes. In this process, I gained a better understanding of structure, especially when handling the transitions in the finishing stage. Before, it felt more like I was building volume intuitively. Now I’m starting to organize these ideas more consciously, and my responses when drawing have become quicker. There are still some more unusual angles that I need to explore further, and I’ll gradually add those in future updates.

Here’s a skull study. While organizing references, I noticed that skull features can vary across different populations. For example, people of African descent tend to show a more pronounced projection in the mid to lower face. Next, I’d like to add a few more studies with different ages and angles to make this study more complete.

I updated another study of the structure around the eye. Out of curiosity about more subtle plane transitions, I ended up doing an extra one. Compared to the previous study, this time I intentionally emphasized the smaller plane changes to make the volume transitions read more clearly.

I drew a dog skeleton, which pairs nicely with the cat skeleton I drew earlier. While reading through references, I noticed that the structural logic of a dog’s skull is actually somewhat similar to that of humans. Basic components like the zygomatic bone and the upper and lower jaws have clear counterparts. The differences in proportions and features between breeds are also quite interesting. Next time I’d like to try drawing a low-slung dachshund as well. This drawing had a bit of a rough fate. Right before finishing it, I accidentally spilled coffee on the paper. So I went with it and brushed on a toned background to give it an aged look. Almost all the lines had to be redrawn from scratch. At that moment my mood was probably as wrinkled as the paper itself.

Just as the title said. will show my "sketch" and the ref i used. Thx in advance.

Hi everyone, I need your help. I've been studying head structure and some of its anatomy because I want to do a portrait of someone with their head in an unusual position, but I can't get the likeness right and the proportions are off. I also want to capture the facial expression. I don't know if I'm doing it right; I'm honestly a little desperate. I hope someone can help me. I would really appreciate it.

I did a crow / raven study another one for the bird series. The way the wing feather groups are divided is so interesting. There’s also a strong connection between the feather structure and the underlying bones, which made me revisit the idea of “form follows function” once again. Every time I draw animals, it never feels like enough—once I finish, I want to do another. While researching, I realized crows and ravens are actually very similar in many ways. But they also hide plenty of subtle differences ravens are generally larger, and their tail feathers tend to be more pointed. Nature is full of clever, rich variations.

This is some drawings I made while studying anatomy, I made a mistake along the way so a lot of the muscle placement is wrong but hey, it looks cool

I tried this after watch the video on the lower back. Any thoughts

I made this drawing showing my current knowledge learned from the anatomy course. I'm trying to figure out if I missed something. I'd appreciate any feedback. Thank you!

Here’s a study of a running dog. While drawing, I noticed how interesting the differences are between trotting, walking, and full-speed running. The shifts in weight through the legs, the moments of suspension, and the rhythm of the paws hitting the ground all feel distinct. Just observing that makes me want to draw a few more studies.
