What a nice picture! I have seen "Waterworld" and I personally found it to just be okay. There were certainly some creative ideas in it. This looks a lot like a giant monster's month. The mountains look like teeth. You spelled "apart" wrong. That almost seems intentional.
You have some wonderfully lush colors in this. I can see the purple influence from the Joy series. It's amazing, given how different those two things are. I guess it's supposed to signify an earthquake occurring. Then again, maybe it's been like that for a long time.
