The leftmost support for the wing section looks a bit rough (at least on my monitor); after looking at it for a while, most of the other edges are fine; I just wasn't thinking about the edges being curved instead of straight. It may also be the pattern making things look rougher than they are.
I'd also make the part that's projecting out the front a bit wider; it looks more like a rudder at the moment. Oh, and I figured out why I thought the perspective was wrong: the supports on the left half of the wing look like you're seeing them head-on, but I don't think that half of the wing would appear head-on, judging by perspective in the rest of the picture.
In any case, it's a lot better than I can do
I look forward to the finished product...
