AP, I really like your NMF technique, and I'm pulling for you big time on this baby!

But, I have to submit some comments for your consideration. Please take them as they are intended--to help, not criticize.
I continue to pick on the accuracy of your lines. This just doesn't look like a Thud. Whose lines are you using? Are you depicting a "B" or a "D"?
The nose is still too blunt, the shading and upper wing lines near the fuselage give the wrong wing shape, and the rear lower fuselage outline is just plain wrong.
Please, please use an accurate drawing. Your artistic skill is way too good to be flawed by a bad drawing. BTW, that "Smith" drawing that John posted is not a good one-where did he get that vertical tail shape??
