Nice job, you're improving tons with each one Top left needs a bit of work and around the aurora borealis (which im guessing that's what it is), you should fade out the stars a bit. Like, where you can see the stars through the lights, fade them out some. The reason for that is because when theres something bright in the foreground, it will make illuminated things behind it appear darker. I'd do it just to see how it looks. Other than that, it's good work. The starfield is great. It has pockets of darker and brighter stars, different sizes and strengths. Keep practicing
