DAMN! It looks like I need to redo it! I hope I manage it intime.
Since you added the bg, you should AA the outline too.
Agree about previous comments; also try to use the bg color somewhere in the sprite.
Just thought the same like DawnBringer. I would add a color between the grey and purple. Or maybe lighten the purple.
But nice overall, works better with the background.
Thanks for pointing that out :)!
But could you explain more on what shade you wanted me to add?
It's a pretty cool sprite, but the belly grey is a bit unfortunate color - with the default theme it looks like a hole/transparency. You could also use an intermediate shade between that grey and the darker colors.
Wow, really guys? Second to last? :/
