Greebo,
I love your ability to work with details in many areas of your skins. You definitely make a plane look good. I find, however, the over-representation of the wing ribbing detail to be a bit heavy. These weren't nearly so evident. Even though the material may be described as fabric-covered, it wasn't the same as we see on WW1 biplanes. It was much more subtle.
This is more a comment on the choice of aesthetics. I think you've crafted them nicely, but that it doesn't quite reflect history. I'm guilty of this myself at times.
I offer an example of a front-line fighter:

You can see hints of the shape on the stabilizer, though not enough to distort the paint. The wings are almost unnoticable. Here's a restored warbird highlighting the details with sunlight. They are visible, but much more toned down.

Might I encourage that they be toned down in the future?
Otherwise, it looks very fetching.
