Late Bloomings

Very well put together in terms of colors and contrast.
The nebula/space-scape is a bit flat in comparison of the planets depth.

What could've been done here is that if you'd increased the shading and contrast also on the nebula/backpiece you would've get a much more harmonical piece that flows well together at a higher state than it does now.

To intensify the glow/bright light here a choice of bringing more stars in the composition might be beneficial. I'm not saying you should add stars all over, just concentrate a couple more around the exposed area to make it pop in a way that really would nail this already amazing piece.

Great job mate, it's all in tuning the details from here, you're insanely good at these space-scenes. Last 1,5 year you've really brought the A-game.
