thanks..but me gonna be hard on meself.. 

apart from the lighting on the planet.. 

one thing i failed to do...is that miserable border of the snow..doesn't look like it's fading into the background and that the planet and the sky behind it. looks like a cut off! would it be fair to cheat and place trees around to hide it? that's the only thin i can think of.. just cover the edge with trees..

i need a softer light..but will 'soften' it in phtoshop as a whole later on.. 

any more?
