Your Gorilla eyes …. flatten the bulging eyes, and drop them into the cranial ridge. use a small pen or dental tool to put an inserted iris into the eye, as you either use an X acto blade to remove the putty curvature of the eye.
Your body is a little too long, and needs to hunch forward, as an Ape/ Primate. Remember, the upper body is heavyer, which leads to leaning forward on knuckle/claw.
I can see what you did with the hands, but the issue comes as that they are not primate hands.- chip off about half of that greenstuff/putty, and drop the thumb back. bob off about a quarter of the greenstuff on the feet, and go back to your source material for the primate feet.
Small, vary small improvements to recommend to you, but overall a great first effort!
