Last sig I made

[MCR__Ftw]

Hey, I was thinking about getting back into the GFX scene, and would like to know where I can improve. I'll post the last sig I made (8 or so months ago).
I would really like some constructive critisicm. Nothing like "you suck", atleast tell me why I suck, and how I can improve it.

Thanks!
