8/10: I like it a lot. great job. My only suggestions would be to get rid of or change the mountain, and to blend the transparency of your planets for that crecent look.
also, purple is good but blue is better. Remind me and I'll teach you the transparency thing and how to make realistic rings around ur planets. :)
Yes, I was going to do one with blue next. I was thinking of that during the upload. Blue is my favorite color, so that'll be my next project. And I'm sorta lost by what you mean about blending transparency, because really, the lighting and shadows are based on the sun's position, so I'm not too sure what you mean, since that's the way they should look. I was liking how they came out.
Great picture. Only one comment: the rings can't be that close to the big planet. It defies gravity and thus looks unnatural. Other than that it's beautiful.
