where is the rust?

You might want to twitch the curves to bring the rust out a little more. That is kind of cool, though. It looks like the standard horror flick scene where the toxic waste leaks into the water supply and creates mutants, or something. What IS that anyway? It doesn't look too safe.

The rust here is right next to the hole, and that green slimy toxic leaks is actually algae. This is one a water tank, and it had lots of wholes in it, and that's just water - I hope lol = ) I will try to play with the curves some more, thanks for the comments guys.

Great idea..
