Good looking aircraft. I only have a couple of "nits" to pick, just to make the markings more accurate:
1) The color scheme needs a red ring around the nose, this goes along with the red stripe and chevron to show it's the lead aircraft of section one, as indicated by the "1" on the side of the plane
2) The rudder markings, when using the vertical blue "hinge" stripe, needed to all be vertical. The red stripe was at the rudder trailing edge with the white stripe in the middle. When using the horizontal red and white stripes, there was no blue and the stripes were limited to 13 total, of equal width and with the top and bottom stripes being red
The above said, I wouldn't worry about changing anything if you're happy with it
