Looking good!
I've always thought it might be fun to paint a 1/1 scale aircraft..due to cost and space I have to settle for 1/72. One thing I noticed in your artist's rendering though; the proportions of the insignia aren't quite correct. It's a little thing, but a pet peeve of mine on restored aircraft. When the bars were first added to the star-in-circle in the spring of 1943, a red surround was added to the entire insignia. This was changed to Insignia Blue after a few months, giving the insignia its current proportions (the red bar was added in 1947, but the proportions stayed the same.)
Here's an example of what I'm talking about. This is the (incorrect) way the insignia is often painted..

And here's the correct way. The difference is subtle, but noticeable..

I don't mean to be a jerk or anything..if you're already aware of this, just tell me to shut up and crawl back under my rock.
