I agree with Bush Baby partly. This is a WIP and although you posted a screenshot it is extremely hard to tell what this is. Is it a space sim, a RPG, maybe a cutscene in a RTS (รก la StarCraft)?
I wrote up a
small article about how to post stuff, you might want to read it. Will spare you some flames.
On another note, I really like the looks of that shot, although the sun could be much lighter. It's darker than your planet now and for some reason, I don't think that's how it should look. Also, lower the bloom on your planet a bit. It's too much to be likeable for me.
