pros-1.Your ambient occlusion turned out really nicely all of your model is described. however if you lower the distance of your Occlusion just slightly you will get a much more refined Ambient Occlusion because some areas such as the top of the head have more grey than necessary. Also think about bringing down your dome in the y axis to give more of a ceiling for the photons to bounce from2. You've captured the essence of the character and it's clear who this is. SHREK!Cons-1. you've given your character less brain space than recommended, to fix that issue you could go back in and sculpt out the back of his head and give that area some more volume(not too much volume or you will end up ballooning him)http://img2.timeinc.net/people/i/2007/gallery/shrek/shrek8.jpg2. your ogre ears seem a bit out of proportion. maybe tighten up the the tube of the ear so you have a slight tapered look.
