Just 2 bands? It would look better if you added more, but whatever, it's your sig.
Not much to rate, though you could use a different font, like band-themed.
UHHHH Dude that sig was made with paint. and u spelled red hot chilli peppers wrong. u spelled it Red Hot peppers.
And u can easily tell u just merged pics together through paint. but im sorry if im coming off a little mean but seriously dude.. put more thought in ur sigs.
One suggestion: Make the Green Day...green? Right now, the Red Hot and Green Day sort-of meld together because they're the same color, it takes away from the rest of it.
