To make sure you maintain aspect ratio, either hold shift while you drag or click padlock between W and H on top bar.
Tick in top bar or click enter when you are done. If you are really good do it on a dupe layer then u can change your mind, and bin it and start again!

If your sky be nice but noisy, zoom in real big and try adding a few px of gaussian blur. I know Paul's way with a brush was more area specific but for me ....well, guess I am less perfectionist !
