Very interesting design, looks good! My only suggestion would be to tone down the aztec-ing. My understanding (and I may be wrong) is that it's just to show the slightly different shades of the construction panels used to build the ship. I see a lot of models that are ruined because of the aztec paint job.
I'm not saying that about yours but I think the different shades should be barely perceptible. Enough that you notice the panels but not so much where it takes away from the overall look of the ship.
