If I could make a few small suggestions... Try to put the shield with number lover so it doesn't cover the aircraft profile. Think it would be better if it covers part of that banner instead. Also it's better looking when banner is below the profile and not above it. You should also try to delete antenna wire, on picture this small it should be almost invisible anyway and the icon might look better without it.
Anyway, just some thoughts on the subject....
