I made this program using Terragen. It didnt come out as well as I was hoping, but I decided to upload it anyway. All comments and advice are greatly appreciated.
I like the (nonexistent) horizon the best: it is completely in a haze, which continues down from the clouds. Very nice. The rocks, though... maybe I'm being too hard or not understanding, but they look a bit too artificial to me. overall, very nice, I like the colors choice.
Wow, it is really cool. The ring of light around the island and the light poking through he clouds looks amazing. Great mountains and cloud shapes too.
