I followed along with the examples, then I did some of my own!
Hello, this is my homework for this section :) Even though this is a ribcage assignment, it was more difficult for me to find the pelvis. I feel like I make it too small and too separated from the torso, especially in the one I made digitally too, I also had problems with the angle on that one. I made many experiments but I wasn't satisfied with any of them. Critiques would be highly appreciated :) @Liandro
Hey, @Mirelle Guillén, thanks for reaching out! :) I think you’ve done some really good work! Solid forms, clean lines, good sense of structure. Way to go! I agree with @Anna Sch, taking a little side trip to the Figure Drawing Fundamentals course could help you see the “bigger picture”. The lesson on Landmarks of the Human Body is certainly a valuable one, and you might also check out these lessons on proportions: Human Proportions – Average Figure and Human Proportions – Cranial Units. By the way, the proportion diagram Stan provides under the "Downloads" tab in these lessons can be a pretty handy tool to keep and consult as you work through your studies even in the Anatomy course. As far as the ribcage is concerned, I really don’t see anything that needs adjustments right now. Good job! Regarding your thoughts on how to draw the pelvis, yeah, I can tell from experience that it’s probably one of the most challenging parts of this course - so nothing to worry about if you’re having a hard time with it at this point. Based on this set of drawings, I’d say you already understand the overall forms of the pelvis and its main relationships with the other elements of the torso, which is great. Adjusting the size and spacing of these elements and building up your confidence on how to match a believable sense of structure of the torso could be just a matter of getting some more mileage and familiarity with the anatomy over time, study and practice. I’d say you’re on your way. Two helpful little things to remember: 1. The pelvis’s height is about 3/4 of the ribcage’s. If we take the cranium as a measurement unit (as in Hale’s cranial units system, which Stan mentions in the Proportions lesson in the Figure course), the ribcage is about 2 craniums tall, and the pelvis is 1 + a half. Having this info in mind can be a good quick way to visually check the size relationships between these elements. 2. The distance between the 10th ribs and the Iliac crest (in other words, the space between the ribcage and the pelvis) is nearly about the width of the person’s hand. In a torso sketch such as the ones you drew here, you could visually estimate what the person’s hand width could be, and then adjust the distance between the ribcage and the pelvis based on that estimation. (The proportions diagram I mentioned before nicely illustrates these two tips). From here, maybe you could take some time to do a little self-assessment and see if you can adjust these sketches by yourself? If this still can’t help you solve your current doubts, feel free to call out again. Best of luck!

Hi. You can practice the landmark exercise from the figure drawing section first to get a better sense for the pelvis. If you dont have the figure drawing class you can also watch the free video on youtube. When you learn to see the bone marks of the pelvic its easier to see how it is tiltet. Hope that will help a bit.

Here's my Rib Cage Assignment side view. My attempt is on the right and I followed along with Stan on the left. Critiques welcomed.
Ribcage construction - First two were from reference, third was made from a box shape. Tried to simplify it's shape and looking back at these I can see a few perspective issues. Critiques Welcome! especially on proportions thanks! @Liandro Roger
Nice work, @Tiger Gayle-Walker! Here's a few things I noticed: . I think the construction might have gotten a bit too "blocky" and rigid, so perhaps see if you can round out the forms a bit more. You can start blocky and use flat planes to establish a base sketch, but then see if you can model it into a more organic aspect later on. . One thing I really like a bout image 3 is that, even though is very blocky, it shows a convex lateral - we can see from the cross-contours that that side plane bloats out, that's cool. The other 2 drawings don't show that as much, they might have become a bit too flat in that area, so see if you can round them out a bit more on the sides too. For that, maybe you don't even need to use straight lines, I think you could go directly with curved cross-contours and it should be fine. . In image 3, the front plane of the ribcage feels a bit too steep to me - as you try and round it out more, this should be eased, but perhaps, even when using a blocky structure, it could be just a tiny (very tiny) bit more inclined towards a vertical. . Perspective really doesn't pop up to me as a major issue. As for proportions, maybe the first two drawings are a very little bit too elongated, no big deal though. . It's really cool that you've tried a construction from imagination rather than just studying from the reference pictures. Mixing up these methods (reference X imagination) turns out to be really helpful when studying anatomy. Hope this helps! Keep up the good work.
