hmmm well it depends on the type of cowboy scene you want. You could do a kind of nice airy day ride thing using beiges, light greens and some blues. Or you could go for a kind of sunrise/sunset look and use some reds and darker blues that type of stuff...heck if you were feeling extra creative or if you could find a stencil for it you could even do a cowboy riding off in to the sunset. That's about all I can think of really.

Well there is one more thing and I don't mean it in a bad way but you might want to consider refinishing that dresser. It looks pretty good now but if it was stripped and refinished it would look awesome.
