Took a long time to do this one, so fullview it to see all detail.
I thought my last spacescape worked out ok, so decided to do another. But I'll let you tell me what you think.
The edge of the planet is way too sharp, you should consider the overcast that would be caused by the hotspot behind the planet. (there where, incorrectly, the shadow is) I don't find the shadow disturbing, though... just the sharp edge. Other than that, great work and awesome brushing. Any special brushes you used ?
