Ar-234, Hurricane, Spitfire/Seafire, Avenger, Dauntless, Devastator, Wildcat, Hellcat, Corsair, P-40 and P-38 and at least some of Allied Bombers are already made.
It
really wouldn't hurt if You just browse all threads here and on old forum.
And if You want to do such technically demanding planes as Me-323 or Go-229, then I can already tell You that
I will be nit-picky when You do them.
So let's say You're progressing, though still an issue of that weird diagonal line above gear covers. On the other hand, You seem to overlook that there is radiator (or something) under the wing. As for the colors, that swastika on tail should be "divided" by black line (dividing tail stabilizer from rudder) and I'm inclined to think that code letters may be too big.
Really - before drawing anything try to actually check what's there, not just "follow the lines".
And overall - contrary to ships, currently there is no "official" upload of FD-scale drawings. It's just that occasionaly Nighthunter is linking drawings to "Condensed FD Aircraft" thread - and He adds there the stuff that is available - and represents highest quality when there are several different drawings of same stuff.
