That's looking VERY good! Great job. We do desperately need a Texan/Harvard...
If I can make one comment from the skinner's point of view, it's generally easier to paint when the cowling is mapped separately from the fuselage, so the cowling textures and fuselage textures don't come into conflict - particularly along the forward fuselage where it's covered by the cowling. Don't know it you've already done that, because if you can't see what you shouldn't see, then it's been done right...
