Whilst this particular concept, to me, seems better suited for a say a banner of sorts, the effects are great. I like the direction of this.
If you can incorporate more of this idea into whatever else you do, I'd like to see the effects. I guess if anything, your lines of color seem to pop off of the stock a little more than it appears you intend do. See if you can work on the saturation a bit.
But I like it.
