not bad for a first animation

gfx quite good. Just try to make an animation flow a bit better next time ok
the other ones ur current hulk sig is quite good.... don't like what u did with the font, the color is a bit weird on some places too, talking about typography, u might want to go "back to basics" with that, because, personally, I think the fonts u pick and what u do with it doesn't look very good on most of your sigs. simple often works best!
