Ooh. Overall the style of coloring is very effective, the pink in the skin makes it look more fleshy and realistic than a lot of other anime styles. It also helps the lips to look more natural with the rest of the skin. Also, the effects you used help the character and the background look really smooth and coordinated together.
The strokes seem to be a little patchy, like on the character's right (our left) cheek; and you can see the specific bands of dark / light strokes really clearly (especially on the shoulders and necK). I think this style of coloring could work really well, but possibly if it were emphasized a little more with even thicker, bolder colors and a background with some texture in it as well. I don't really use colors, so I can't claim to know much about how to use em.
I really like how the hair looks, I think the new style is most effective there.
I tried to make him looks more realistic ^^" for that reason I changed my way of coloring...as you said! it needs to bolder colors !but this new style is SO hard and take alot of time so I cant use it alot ==" <<I don't have enough time.. thanks rusky
