The paint work is tremendous!! I love Jugs and this is a fine example!!
This is a well known aircraft...even Corgi did a diecast model of it!...you represented it well.
Yes, there are a few issues with the decals.
So, just for clarity:.
The "stars and bars" are indeed wrong way around.
The wing insignia may also be a bit too far forward. They should be closer to the aileron gap.
The Pilot info block is never way up there. It should be below the canopy line, just ahead of the pilot entry.
[see photo]
Same issue with the noseart name - it can't be read on top of the cowl.
Its basically for the benefit of those standing on the ground beside the aircraft, inline with the noseart pinup.
This name (Rozzie Geth" is quite long and does stretch onto the upper fuselage, but not by much. [see photo]
The side insignia (and 'C') are too high at the rear...the "horizon" line would be the vent doors.
And when they switched to Insignia type3B (the one with the surrounding blue stripe) they often moved up and rearward
with only a small portion of the bar on the vent door. (I don't have a photo of the aircraft that shows, so I can't be sure)
I can't tell, from the photo, if there is a wing walk strip (the black anti-slip stripe) because it's partly hidden by the invasion stripe.
But I do see the "No Step" warning block (which is missing from your model).
Its that red area that the pilot is avoiding stepping on.
