Not sure if it's just me, but I keep looking at the orange strip in the second sig more than the person. Overall they're really nice, and I'm particularly fond of the last one. Also, if I may ask, what brush style is that on the third selection? Did you create it or download it?
the third's brushing if you mean the backrground is a dled brush but if you mean the effects that look like fire, that's using default brushes and smudging and displacing and liquifying and enchancing them to get that outcome.
