Gee you color in photoshop right? from the looks of it you color directly into your ink..what you should try on your next piece is load in your ink...set the inks layer to multiply. then create a new layer underneath your ink layer, use that layer for your colors...that way your ink and colors blend better and you won't get those white spots between ink and color (as you can see with the bottom of naruto's shoe) hope this helps buddy and keep it up and your colors will match your sick lines. coloring is not that difficult,it's just a lot of trail and error.
