Great job on updating those skins Fencer, there is some good detail on them and they are all, the USAAF P-51D in particular, nicely weathered. I'd like to see some of your Firefly skins.
There are a few niggles I have though;
On the P-47 across the top of the rear fuselage the top 20% of the USAAF insignia gets stretched in height by the shape's barrel distortion. I usually reduce the height of the top of the insignia circle about 20-25% to compensate for this. Also I think the panel line dirt and gun soot could be toned down a little.
The grey and green colours on the RAAF P-51D look a little pale and washed out to me.
