Looking good, adjusting to what you are looking for.

If your not done with the tongue go to next paragraph. However, you can always use YOUR tongue as a guide since we share quite a bit of the same features. The tongue is a muscle and should relect as such. The size is okay it needs to be a little thicker though. Also these guys eat a lot of rough material so applying a slight dis map on his tongue would reflect his diet and only add to the realism.

Im also looking at the mouth still and there is just something not right about the pose. The jaw does not look correct. Just like like in us humans, the ape's jaw extends back and up behind the check bones. At this point the pivot allows the jaw to rotate downward. However the lower jaw on your model appears that it is not pivoting but more like it is just simply being translated down and rotated a little to give the impression that it is opening. If this project is VERY important to you to do it realistically than reexamine the mouth. Even get an anatomy book like Animal Anatomy by Goldfinger.

Since you are making him look this way your focal point is his mouth. So you must get it absolutely correct otherwise people will say something is not right. You can exagerate as much as you want as long as it is believable.

Also you had a good dynamic angle on him before. Why did you change it?

THIS IS MY CC AND I STAND BY IT.

Keep up the good work, you still have time.
