I like it, but it seems that the white is too bright.
My thoughts exactly.
It's almost like you need 3d glasses to view it correctly.
Here's a little edit with just the white on the teeth and eye. I reshaped the head a bit. It looks a little meaner now. I'm sure you weren't going for mean, but that's just me...lol
I wish you luck in the challenge.
EDIT: After the edit I realized this was probably a plant eating dinosuar. No need for teeth like that...lol
