thank you very much, I try to apply your feedbacks in these new drawings. should I go to the next lesson (landmarks)?

Hey, @bycristian123, these are really nice! Very cohesive and good sense of form! I agree with previous comments about showing things as if they were transparent, so that you can build the drawing up like a sculpture, envisioning the 3D space all around and how each part connects to others in the structure. Try to be as clear as possible to yourself about which forms you’re using so that the drawings have an assertive sense of deliberacy and design. Along with that, since drawing transparent forms can create an overlapping mess of lines, you might also wanna create some visual hierarchy: use thinner and lighter lines for whatever is farther behind or “hidden”, while keeping anything closer or “in front” in bolder lines. I’m attaching an example over one of your sketches. Hope this helps! Keep up the good work!

These look good. Something to consider- a challenge and big benefit whenever constructing structurally is being able to see through the other side of a box or other simple solid form, as if it was transparent and made of glass. So maybe look at your drawings and consider if you can see through to other side after this exercise. hope that helps.

At the end of the video, proko mentions a critique system, does anyone know if it's still working? https://www.youtube.com/watch?v=3uEtdDvK6Xo

Ah so cute! Your proportions and line quality are good too. If you are practicing structure you should try your best to show every side of the forms you use, like you did on the horse's pelvis. I can see top, bottom and side planes. However, on the rooster for example, I can see where the cylinder of the neck attatches to the body but not the head. If you added a top plane I could see where the sphere of the head attatches to the cylinder of the neck. Make sure you draw through the shapes to show their perspective and where they attatch to the next form. I hope this makes sense, and it is harder than it sounds. I'm still struggling with it.

It's the wild kingdom of sketching form. They have life and flow. You use basic shapes great; they overlap correctly making for good proportions, depth and anatomy. and the hippo and elephant are frustratingly adorable. Frustrating that I cant hug them and watch them run around. I do see one problem. where are the monkeys? They're only the greatest animal to ever live. other than that great stuff. Well I'm off to watch some youtube videos of baby hippos and elephants.
