Very cool! I love the textured background. If I had to nitpick, I would say, If you ever do another one, try toying around with setting the ships at different angles. This can add some of that extra dynamic that would make is "shine." Plus, being a wall hanger, people are going to look at it from the side, and rolling them a bit can show the ship's profile a bit more.
Awesome job! Definitely a conversation piece in your house!
