Alright, made some changes to the front sprites and did the back sprites. Still need to make some more changes before doing a final submission tonight. I lightened the gray, fixed the feet so that it's facing more forward, and made lots of little shading alterations.
I've never done back sprites before, so any advice is greatly appreciated. The shading on the clouds is especially subject to change.
I've become strangely attached to the shiny coloration, so unless anyone has any groundbreaking issues with it, I might keep it.
