I like the first one, but she looks a bit squashed betweein the pink and blue effects. The smudging of the pink to the left is nice but then after that its straight black for about a 1/3 or 1/4 or the sig.

Not as keen on the 2nd one, all the brushwork looks random and is ontop of the render. That upside down L looking brush looks pretty dodge because it looks like its just the circle brush thats been brushed up then right but not very smoothly.
