I think the texture needs more warmth. I also think there needs to be more variation in design. I see that you have some type of rock formations at the top and pelvic area, but that's it. Perhaps you could put some on the knees and forearm to satisfy the lack of variation. Additionally, I think the structure of the body seems kinda like a balloon animal. May I suggest increasing the size of the patella area? Lastly those feet are huge and kind of connect weird at the ankle. I think most of the issues will be cleared up if you refer back to some anatomy diagrams. I hope I wasn't too harsh. If I was, I apologize sincerely!
