Hi @Sita Rabeling, I think the drawings looks really nice! -To "see the planes" it helps me to imagine touching the forms. It might also help to imagine a box around the subject. I imagine the box by imagining touching it's sides with my hands. - I think you can give the achilles tendon more solidity; make it a little thicker, and a little boxier. -Not a calf critique: In the back of the thigh you have a few overlaps that I think might be off. The contour for the glutes should overlap the hamstrings. Cheers!

@Jesper Axelsson Hi Jesper, unfortunately I don't know much about shading right now, but I will try to answer your questions ( please let me know what you think, so I can verify what I think is going on here). 1. I think There are two bumps next to fibula, the one in the soleus side, I think is soleus striations (because there shouldn't be any other muscle there), but the second one above the peroneus doesn't seem like striations (they would go upwards, but here it just a bump). Is it some bone underneath that makes the peroneus bump on that spot? 2. I think that because the lateral side of the gastrocnemius is smaller than the medial one, we would see a little bit of the medial column too (from what I saw on the 3D model). Your shading seems very good to me. Looking forward to your reply :)
