Looks VERY good! I might recommend though finding an image of actual stained wood to use as a background. Something dark and rich.

What I find myself interested in is the idea of simulating a 3-D effect with printed graphics. So for example you could print out an extra copy then cut up the parts and mount on balsa supports to give it more depth. I'm thinking of doing this with the engine on my Snipe. It's a technique artists refer to as a "tole."***

(***Thanks to Allen for the correction on this word. I believe he may have been the person who originally mentioned the idea to me)
