Ok so clearly the front doesn't look even remotely aerodynamic. To that effect, I've made a new version that makes some changes. It's still fairly similar to the original design, but it should be somewhat more aerodynamic looking.
Personally I would go with an even sleeker, more aerodynamic design. Get rid of all straight surfaces and make sure everything is rounded.
With a sculpting tool, that should be pretty easy to achieve, same with nurbs (more work to get a complex shape right, less work smoothing the roundings like what is needed with a rough sculpt once the shape is correct). To get the polygon count down to acceptable levels for ingame use, a retopo is needed anyway, no need to hold back on polygons for the initial sculpt IMO.
I still think the rounded wings clash with the still boxier cockpit, and the anciliary fins which are straight.
Wingtips are to thin IMO compared to the bulk of the ship body and the base of the wings.
Air intakes and weapons could be integrated better to the body, more "aerodynamic"... at the moment these look rougher than on any WW2 era airplane (which of course where way more aerodynamic and advanced than most people believe, there is a reason why the WW2 Vintage fighters are still the fastest non-jet non-turboprop planes on the planet and used in air races).
On the positive side, save from the hard edges that scream "box modelling" to me (as opposed to sculpting in Blender sculpting mode, ZBrush or 3D Coat), the model looks more aerodynamic now.
Hmm, ok, well, I will probably have to make changes then in that case, somehow. I think what I'll probably do is just soften most of the edges to give it a more curved look (many of them are hardened right now).
I'm still in the process of things, and since I have a hand injury to deal with (long story), I'm a little slower than I'd like. In any case, here's some pictures of a preliminary texture set I've applied to this model in Unity:
I personally prefer the top one, but both are possibilities at this time.
This pic is more of a "for fun" pic I made:
Love to hear thoughts!
EDIT: Since it's somewhat tough to see the aileron textures, here's another close up shot of the aircraft:
EDIT: Ok, clearly that picture isn't working. Here's the link:
