Here's some pics of Son Goku from Saiyuki I colored C'nC V.1 V.2 V.3 I did all of these on Paint...yes paint, just so you know :D
I think it looks ok. Wats the difference between the second and third 1? Suggestions: Uhhh...maybe u should color the boxes...
Interesting choice. Try shading the colors next time. It looks good, don't get me wrong, but shading them in will make them stand out even more.
They all look ok. suggestion: Color all the candy you see, its boring and non-attarctive to see some candy colored while others not.
Compared to the tones of the original art, the colours you added are way too sharp - lower the opacity so that it's less sharp.
