Simple answer for that.. they aren't natural. Honestly though, I think that's about as good my planets are going to be for now. I'm not exactly the most skilled photoshop artist, so they'll improve over time.
**EDIT** And some people were asking if it was done in bryce.. the only thing done in bryce is the green part of the tornado/laser.. whatever you think it is. I'm leaning more towards laser now..
