Good job Brooke!
It looks pretty fine to me. I trust you with how the colors appear. However, they are supposed to be blue and red, pretty much like in they are in the RAF roundel... so not orange. Medium blue and medium red sound good... as long as they are not dark. The black planes have to stand out from the blue.
The word "September" is quite close to the edge, the bottom of "p" even touches the black edge. If it is possible, that text could be moved inwards, like the other texts already are.
The bomber on the left has some blue thread on its left engine, which makes it look like the engine is breaking apart.
