I like the color tones in the sky. I also like how you have sharpened it with out leaving any noticeable traces around the wings. Even if you have changed the sky's color tones in post processing I do like the outcome, I hope you do well with this photo!
A Classic wth a nice feel to it. I note that your image size is just 74KB. If you would have save less compressed (up to 150KB) - you would elimineate some or all of the banding in the yellow sky. It is most noticeable in the top left. Still a great submission.
