I like the simplicity of it.

I don't know how this would work but I'll just throw it out there...
If you're going to have a glowing red trackball you don't really need the gradient behind the kanji. That thing will glow just fine on it's own.

I like the idea of the Kanji but maybe make it bigger,
red and move it or the trackball to the center of the kanji.
Make the Akuma and Ryu
Bigger. It just seems that the MAME has more priority than the characters. If that's the way you want it cool. Personally I would lose the MAME in the background. Something makes me think you're more of a SF fan than a MAME fan.
