Texture on the planet is good. I would try to use a bit less stars in the background and then I would try to achieve more texture on the rocky foreground. You can do this by pulling off more paint with the magazine paper and texturing it as you pull up or you can achieve highlights with a palette knife by scraping the wet paint.
Really like the concept of this painting. Good job on the moon. You might practice on using your black on your arch to create some shadows and crags to give it some depth. Keep them coming!
