Got a pic of some dude, then added a brush or two? Please prove me wrong cause that's what I'm thinking. If not, I can't rate until you show original stock.
V1, 2 and 3 are bad. 1, doesnt flow at all, the other 2 are really choppy. For the 4th one, I like it, looks likes shes accually blowing the fire out of her mouth. I also like the colors you added in and the effects on the hair. Simple graphic here, and nice one. Good job. +10
