hmmm definately agree with the to much pink, by that i mean you should differ the shades a bit. like the pink BG top right you should make that a lighter shading of pink bottom left and top left maybe go with a darker pink? this way you still keep the pink idea but make everything stand out a little more without ruining the basic idea you have going. GREAT JOB on your signature, it's enjoyable to look at besides the to colors of shading on the right and left bother me!!!
the flow of the colors are done well, but im not a big fan of all that pink mate. good text placement. nothing to say about that. decent all around.
Too.. much.. Pink!? Never! It looks pretty cool, you seem to be getting better with your anime tags each step by step
