I like the concept, but maybe all around the paint you should add a little form to it by making it all darker on one side and brighter on the other. Make it subtle, but still visible. Obviously increase the effect for places where the paint looks thicker. If you want an example of how to define the paint (though I'm sure you understand) look at Fade's sig:


Clearly you'll have to make yours to a lesser degree than that. I also think that, text-wise, you should just use Lumix. I'm doing this sorta thing on a larger scaled piece right now
