I like your style of drawing. It's unique. I really like the way you've done Vegeta's hair but I don't like the way his eyes are drawn. If you don't like the colors, you can always have someone quickly adjust it in Photoshop for you if you don't have Photoshop. It'll take like 30 seconds.
I knew you could use Photoshop to change Hues in colors, but what I don't know is how to change just certain aspects of a picture, like the little stuff, I only know how to change the colors of the whole of the picture and I don't wanna at all! XD If I knew how to change small parts then I would have used Photoshop on it a while back, as it is though I don't want to use a digital enhancement with a traditional art unless it's completely seperate from the Traditional art because there's no way you can get that grainy affect in a digital surface so if I changed the color of his olive pockets to the right color, even on a seperate layer, it would look really out of place.
Actually, if you select an area with the laso tool and then use the "adjust hue" feature, you can keep the grainy effect and still change the color. YOu can also adjust the saturation and darkness. It will still look traditional after all of that.
I don't really like his eyes either ^^!
