Size: Not, sure, what ever fits best. Like the one at the bottom for the sig.
Image: Like the one below, I would like three Pokemon to be in this order:
Cobalion, Virizion, and Terrakion
Colour Scheme:Same colors as the pic below or something that you think seems better please! ^_^
Text: "Fistodragon" without the quotations in a decent size font. And for the color, suprize me!
