Paper Sonic

[theguy]

From what I have seen on the PM style is:

1. the ones with less animations get shading.
   
2. there are two pixels on the outline, only on the outside.
   
3. the colours are quite dull but saturation wise you have AA on the lines.
   
4. the eyes have to little rectangles (there are some exceptions but only a few).
   
5. and the anatomy depends on the character (like because Mario is a fat man, he has no legs, but for someone he is tall and slim he would have legs).

I hope this all helps =D
