The first two views don't show much besides the texture but the last one you've edited gives a more perspective look, which from that look it doesn't look bad

One comment I have is that the thickness of your model could be increased because it's abit flat like aztec already mentioned but maybe you've tried to give it an aerostatic shape so it coud give the impression when being ingame of a high speed aircraft

Besides that little detail, keep on updating this, I'm curious who this will turn out eventually ^^
Btw, the polycount untill now could be increased because your model is lacking detail. The amount of polies could be increased till 1000-2000 max. which is quite normal for these days models.
