, or if you don't like that one and can find another picture of Mewtwo looking ready to wreck some havoc, more power to ya!
Color Scheme: Red, Orange...basically bright, hot colors
Text (opt): "You've yet to see true power!", and then Larvinator in one of the lower corners
Additional: Kind of themed around fire, like Mewtwo's coming out of a blaze or something
Avatar?: Yes please :D
If I'm being too restrictive, feel free to omit some of the ideas as you please; you're the artist, and I'll be happy just to have something non-craptastic to put in my sig. XD Many thanks, you soaring spazz. n_n
