Wow…amazing sculpt 
Alex, without doubts a work made with passion and devotion… I think this is one of your Best! It’s the true.
aw man, i love this gorilla sculpt. great job of giving him that kind of funny look of boredom that they have on their faces sometimes—usually with some leaves hanging out of their mouth. this is the best thread on this forum hands down.
very well done. That skin detail and face detail is expertly done.

Did you create the head and then attach it to the body? By the way your work is some of the best ive seen. Amazing job.
that is some sweet work. what else is there to say.
Also this shot is quite suggestive. 
This guy should deserve a next step of work… an insertion on a background and a render shaders etc.etc. Do it Master Alexleila!

Seeing your gorilla makes me proud of nature! Please go on!
