Looks cool!
A couple comments though... the atmosphere's glow is a bit to big, the world is missing clouds, and the lighting could have a little more contrast, and there seems to be one of theose "things" (what ever they are) in the planet with three legs sticking out. :p
I like the galaxy in the background, is it a backdrop or is it also made in LW? The flares look squashed which makes me think it's a backdrop that is supposed to be wider.
