EDIT: Completely changed the bottom part of the picture. My terragen skills sucks... ...they are not worthy of attention. But if you really want to see the original - here in scraps... [link]
Looks pretty crisp. I love it. The lighting and the choice of colors is excellent, too. I took a look at the terragen one, and you were right. This way is much better. Stick to what you do best, at least, until you get some more experience. I don't think I'll ever know how to make one of this spacescapes. Stay cool!
