I absolutely love how you made her hair so big, and you had a vision of how she should look, and you did an amazing job executing it!! Plus, I LOVE your shading! the only thing i would think about is that the arms look a little too short for the chest! I also love the idea of the striped tights/leggings. The big smile is great, but i also think that the expression might seem a little too "akward" for pinkie just because she has that "i don't care what anyone else thinks of me" appeal! anyway, GREAT job!!!
