Sharper focus and higher contrast could have helped you out a lot here. You have various shades of grey, but with more contrast your blacks would be black and your whites would be white.
The idea meets the challenge, though doesn't hold my interest for very long. The lighting looks a little dull. This could be caused by the camera underexsposing to compensate for the bright snow.
From the thumbnail, this looks like a series of airplane jets. Interesting, I ould have panned to the left to capture the bird's track on bottom left, minimizing space on right.
Neat idea. Definitely shows a pattern! Few things I would have done differently - 1) fix the white balance, picture is too dark and gray, 2) crop in a little more to better emphasis the pattern, 3) sharpen it up a bit - texture contrast of the snow and pattern would have been cool. Good try!
