And what do you think?

[Supah]

It looks good though I would advice against using lines to outline shapes

[BLOWHARD]

NICE But what Supah says about the lines

[JMSmith]

take no notice of them KF,

we all started that way your work show lots of promise

Hello kampfflieger,

the wing base is still curved.
Naturally, the writing and the U.S. national markings.

Greetings

The wheel spats look as though they are flat sided and should be much more bulbous, extend the highlight and shadow to give more form to it.

As for the edging I'll use it in some places, the old outline but a healthy gaussian blur and drop the opacity to increase the subtlety.

Keep at it Kampf. Though I agree with the posted comments, you are miles beyond anything I can do. Lots of potential here. Give us more!
