Good thought in the composition but....looks somewhat dark, there's very little detail in the aircraft because of the dim lighting. The aircraft are at an akward pitch as well. The horizon cuts the pic in two, it's too pronounces. Again darkness masks ant ground texture detailing. I may have added a bit more density to the clouds as I find  small puffies as cloud structures look simplistic and unappealing. Brighten it up, create more realistic aircraft positions and denser clouds and you've got a nicer pic.
