Oh Hell Ya Man! I really like it. The best part is how the arms are spread out and makes it look like she is workin' hard to push her hands back together. How long ago did you make it?
Of the two sigs I've seen from you, the backgrounds have been almost the same, they don't really fit the render, they are really busy/cluttered and all over the place, and the colors are bad. Both of the renders in those two sigs would look better on a dark background, but you have like a "grey" and by that I mean in-between dark and light background and with bad colors...the effects on the render's hands would stand out and look better on a dark, simpler background. Unless the SOTW was at GR, I wouldn't brag about winning anything with your sigs. If it's a good sig, people will think you're stuck up, and if it's a bad sig, people will assume you think you're good but you're not, and there's no doubt in my mind that the forum you won that SOTW at is either an underground GFX forum or a forum that isn't entirely GFX and has a single GFX board run by gfx "noobs". So try to choose some different colors next time, and go for a simpler background. That doesn't mean like a paint bucket background, but not all this grunge brushing lowered opacity cluttered madness.
