its my first shot at a Space scene, only problem is, i'm having a bit of trouble with the whole nebula's and stuff, although i kinda got the planet part down .
the star field needs more work, the stars have roughly the same intensity and they dont look randomly placed...as if they were put there aliged to some sorta grid...the planets' atmosphere need to be faded at some place, like this (randomly chosen planet) has [link]
