I ended up getting lost because I did the water/land thing backward, but as usual, I cheated my way with my digital art and ended up doing it my way. I don't think it came out so bad. I also did something nifty with the clouds by using less of a rough edge and refraction. I also did a two-colored atmosphere based on the color scheme, which probably isn't scientifically possible, but oh well.
Hopefully you like.
