sorry, i always do that
now for the pointers and good things
-its VERY good for first space
-the nebs look pretty cool, apart from one that looks like drop of water
-you put alot of effort in
-next time, on the render, show more of it, maybe 1/3 of piece, and have some surface map on there, and some interesting terrain
-try to make the transition between sky and space smoother, and have some black in there, make it realistic
-i like the texture on the top planet, it has a cool looking thing that looks like a building on it
