Color Comp for mailer.

Finally posted a piece of my own art on here, lolz.
Anyway, below is my rough color comp for my mailer. Like i've said before, it's my idea for my mailer. I intend to paint it with watercolors, but since im so sketchy with that sort of thing, I wanted to do a comp or two in the computer. Any suggestions or comments on it, i'd be glad to hear.
I'm thinking of sticking to these three colors, golds, blues, and pinks.
