This would make a perfect addition to the little toys one finds in certain brands of chocolate eggs. I enjoyed how you have chosen to represent the organic form of the chimp, I think you've made some clever choices that make this object easily identifiable.

The form has many intricate parts that at first seem simple to model but on further thought show that you have put considerable effort and planning into the task.
This brings me to a question, if I may?
On the chimps head - lower portion of the face : I am perplexed how you were able to produce the surface(the extent of which holds the mouth and part of the nose) while maintaining tangencey with the upper face - which looks to be a different surface?
Perhaps your using MOI V2?

Thanks for sharing your work,
