That looks beautiful, Orin. Once again, I'm impressed by what you come up with. The curve on the side kinda screws up, though, although I suppose that's hard not to get (I know that whenever I try to make a curve, it gets all pixelated and weird).
EDIT: Oh noz, I've used that same planet image in a sig >_< At least I colored it differently:P
THEY TOLD ME I COULD BE ANYTHING SO I BECAME A SIGNATURE PLS HLP
Yeah, I don't really know how to get past that other than just getting up close and smoothing it out pixel by pixel. I'd do that, but I don't really care that much.
Basing signature's on Sleipnir's work turns out awsome-like when done propperly. Nice one HF, love the way the colours to the left blend into eachother.
