This is lovely! =)
Agree with previous crits; you should also fix the sore light-to-dark transition on the rocket.
I know exactly what you mean Ellian. I textured the planets without considering the surface angle of the spheres. I'll fix this later along with the crit by Faceless. :)
The way you shade the planets makes them look flat.
I dunno if you see what I mean, but they look like balls until you reach the brighter part, as if you cut the sphere.
Otherwise, these textures and colors are lovely. :)
This is a very cool image, but you've got some serious banding issues going on with the bear. I'd also recommend using one of the blue shades from the windshield for the secondary highlight on the bear, as the purple is much too dark, and too close in value to the seat, which is making that area look muddy.
Great! Good stars!!
