Wow! Very sharp! Where did you find the subject with a nose art image available at that scale?
My suggestions/comments:
- tail ID numbers look a bit too small - extend them downward
- nose art on both sides? Usually its only one side; your images show the nose art on the side opposite from the example.
- wing insignia (probably upper and lower) can be increased in size (20-25%) from the size of the insignia on the fuselage booms.
- I'd add rivets to the vertical tail surfaces. There were 7-8 rows of rivets, horizontal and equally spaced on those. (run them all the way across, even through the rudder; indicating the rudder surfaces were metal not fabric as many earlier war designs).
- does your template have a extra gun port? I see a gun port on the right side of the nose but no gun barrel sticking through it.
Great job! Did you figure out what waffle's writing says? I agree its really a nice touch.
