Begginer to zbrush - some anatomym sculpts for critique
Hi guys ! I've been drawing for 3 years now. I'm mostly a character artist/concept artist. And I wanted to improve my form/anatomy in 3D, because It's a lot better and clear way to understand it, but my sculpt lack in some places, and I don't know how to progress from this point. If you guys have any tips on what should I focus next, just tell me
