Just posting this here so that I know what to fix on a piece if required?

I edited the piece based on what some people said; the sky was sketchy before so I redid it, changed the colors and worked with bevelling. It's the same sky used in another piece in my gallery which was approved, but with different colors.

I had a gradient effect in it, so I removed it, I adjusted the palette to remove partial transparencies and to lower the transparency count to 1 since for some reason it was more than that? It had over 1000 before, it's down to 250 or so now.

I did not use blurs, or any other type of effect on it that should make it blurry etc.
