1) As Rhade wrote - learn to use "edit" button. It's one thing when You made a comment, and next one several days later while there just so happens to be no other comments inbetween, and completely another when You just make several posts in a row - then it's effectively spamming.
2) Not bad, but remember that elements of wing mechanization (like these little "L" shaped things under the wings) should be outlined in black, as they are not carved on the wings surface. And I think that nose should be more downward-pointing, while shading on engines needs refinement.
P.S. It's up to us, the viewers, to declare if it's good or not.
The websites I come from don't care about posting like that, but I'll watch it from now on.
And thanks. I was comparing the drawing to a small Japanese plane and added similar details. Everything down to the panels on the wings is correct. I think the nose is perfect, it was much flatter in the first run but I made it more round and sleek. The wing problem I will fix, you are right. I am not 100% sure what I can do to the engine shading, but I'll see what I can do.
For future reference I will not draw huge aircraft like this. Not even Luftwaffe ones. Ugh, so much work!
Okay, there's my airplanes. I have updated the other two to match my new skills. Any more improvements will update these posts.
