Whoa, that's really good. I'd really like to see it as our banner. Plus, you didn't go to crazy with effects. I think it's great.
Hmm...I like the smoke effects, but mirroring the render/stock wasn't a good idea. And I don't like how you changed the whole sig into one color...try to keep them natural. Try to add some text, too. It's not too bad, but not too good.
the reason why i mirrored it is because that it had a big blank spot next to it and i don't really like it like that Click my Roxas sig to see my forum
Well, you could've just centered the render where the two renders in this one meets (like where the end of both of their keyblades are). And you could use text across the middle.
