Toxic Waste - concept, rough painting

I wanted to paint something non urban this time for an environment. I didn't really know what to paint subject wise except for "non-urban". After some random splashes of paint on the [digital] canvas, I ended up coming up with toxic waste flowing in the foreground with some sort of mountain and part of a city visible in the background. I figured with toxic waste, there's chance for mutation which would lead to some sort of toxic waste monster. Then again, this is my imagination running wild haha.
