Honestly, I like the style without the outline, except where his chin is in front of his chest, that's where I'd put a light grey outline, or try shading there. Looks good :) Also, not sure if you know this or not, (I didn't know at first either, someone else told me) but you can upload directly from the 3DS on the web browser... hopefully I'm saying somwthing helpful, or I was apparently the only person to not know :B

assuming this was from the 3ds of course. guessing by the resolution, no.

I did know that, thanks though. I did make this on my 3ds, but the resolution got messed up somehow. Thanks for the constructive criticism!
