Firstly, I sorted out the major problems using corrective blendshapes, like her shorts and how crinkled they were. I went back and tweaked the buttons, chest and hair as they showed up even more when everything else was neater.
I have added one more expression to her face with blendshapes so now she can be 'happy', 'sad', 'angry' and a 'puff' I thought I could use puff for when she smells something foul - like the Bog Goblin.
Secondly, I have made her eyes as blendshapes to help push expression further. 1 - Both pupil and iris constrict. 2 - Both pupil and iris expand. 3 - Pupil only expands. 4 - Pupil only constricts.
