Here's my contribution...
Hopefully I didn't ruin the style too much, lol. I just tried to address a few issues with the pose: moved her center of gravity a bit, made her slightly taller, and added a pole instead of a wall. I felt it might be less weird that way. I also tried to mess with her face a bit. I widened it by a few pixels to add more depth and messed with a few of the shadows. Hopefully the smirk shows a bit more this way. I also tweaked the hair a bit, although it's nothing pro.
Good luck and have fun!
EDIT: The Top-hand needs work, btw. I left it alone, but it's not ideal.
