Good terrain and color. I see you got the lighting in terragen to look like there was an eclipse before you actually "put the moon on the sun", so to speak. My only complaint is that the eclipse seems a little unrealistic. It is a little too textured and flat, and I think it should be a little darker.
the terrain looks very good, but the eclipse doesnt look right. The actual moon itself looks very textured and the way it lights up the mountains looks like its actually IN the mountains. It looks good now, but fixing a little bit would go a long way.
