I would shoot myself in the leg to have your skills at graphics... Thats a nice banner like all the others you've made.
It looks like there are too many things overlaying each other. It draws away the focus of the render.
I like the bright colors. Makes it stand out among the gray scheme of the boards and the other sigs that tend to be done in darker more subdued colors.
I like it, just that the asiatic girl doesen't pop up a lot, because of all the bright colors. I prefer the on you have on right now but this one is cool too
