Very chaotic. I don't care much for those, so it's probably unjust if I rate it 3/5. Good job though. Maybe you could tone down the chaotic signature a bit.
Actually, there is absolutely no Topaz or anything of the kind in this signature. The original stock was hand drawn and then edited in PS by the creator, so that's why it has that look.
Looks way to busy with the fractal or what not that you used. The text isn't to great, the overlay or whatever you did looks bad on the ride side of the words. There just doesn't seem to be any flow.
Actually, why don't you lower the opacity of each of the renders. You can't see magic really. It's usually smoke, or something. So try that.
Uh? Magic is whatever the **** it wants to be. It can be a ****ing fireball if it chooses. No, it's not. It's just the fact that it's hand drawn that makes it look like that.
