i like the second one, but it's rather low-resolution.
ASPARTAME: in your diet soda and artificial sweeteners. also, it's obviously completely safe. it's not like it will cause tumors or anything. >.>
always remember: guilty until proven innocent
The top one, because to be honest, her ass draws too much attention away from the piece as a whole. Take out those fragments on the first one, and it's good.
If it was your render I might respect it a bit more.. but to me it just looks like some brushing for lighting.. a few tentacle things and some little random balls of light you added. And what are those random yellow things floating around? Sorry.. not into this one..
