As pretty as Il-2's graphics are, it's a crying shame the skinners don't do a better job with their schemes.
Minor detail on that P-39 with the size and positioning of the S/N on the tail, but those little details are the ones that REALLY make a skin, especially when there's plenty of photographic images to work with (having done the Black Sheep's 17883 and 17740 for AH, I HATE the Il-2 skinning community's work for those two birds. Too clean, not faded enough, missing overspray areas, no old-style roundel on 17740's port wing...).
