The shading style is incredibly stylized and eye-popping. Your anti-aliasing is also smooth and seamless except for the odd bright pixels on the bottom of the leg and the edges of the ears. I think those bright pixels could be turned into dark anti-aliasing instead. Gonna fave this so I can study the color scheme a bit more later.

Wow this is really cool :o 5/5

I agree with Sooba. It looks like this was intended for a bright background, so I think it'd be better to display it against that instead of the transparency.

The colors on this are fantastic!

 Nicely done!

 I really really like this, but the noisey pixels around the lineart are keeping me from loving it.  I'm refering to the bright pixels that pop out around the head/ears and bottoms of the knees. I also see a single bright yellow pixel on his left side. 

Get those and it'll be perfect. 

 Yeah! Low poly feeling is awesome here!

It almost looks like an early 3D model with untextured, flat-shaded polygons (like Virtua Fighter). Except this sprite has the most voluptuous knees I've ever seen.

This is perfect, I love it.

 so great!
