Good BUT
Excellent work with a well crafted scene the planet has a wide range of textures and craters give phenomenal realism the lighting is appropriate and the contrast with the shade of the test asteroids.
The only thing I would advise is that we work with is very intense gamma the gamma is what increases the number of particles if used properly can increase the realism of an image, but excessive use makes for thousands of particles throughout the image and these will be as mirrors for the light source
redirecting and damaging the lighting and textures as in your case.
But in general all is well hopefully has been helpful and have it always concerned when performing jobs such as these.
