Grain, Compression, Noise Question

Here is the photo I have questions about:
I am pretty sure it will get rejected for "grainy sky" "compression" etc.
Now the problem I have is that I have applied no compression and the original is not noisy at all. All the above problems are results of the editing I did. The photo was naturally taken through thick glass and contrast had to be significantly increased which made the pixels to "fall apart".
Is there any way to fix this issue?
Thanks in advance,

Try converting the RAW file to a 16-bit .tif first, then do all of your editing. Once you've finished all of your editing, convert it to an 8-bit jpeg as a final step before uploading. I find this helps limit the banding/color gradation in the sky you can see in images such as yours.

Thanks Dana for the quick reply. This is exactly the way I edit my files, RAWs are edited slightly in Lightroom, thereafter in PS but the files I open directly from Lightroom, they aren't converted to jpeg at that stage. I do my editing with levels and curves in PS, resize, sharpen and as only a very last step I save them as jpegs (100). I guess there is just too much editing needed here and the file isn't holding enough data.
