From the murky depths. (update)
This was an experiment and practice using corel painter. Wanted it to look like they were coming out of oil like water.
this prompted me to start a "nightmare fuel (low octane)" collection back when I first saw it. Nothing else is in that collection with which to compare it, as I'm not on this site enough to have much in my collections, but nonetheless I thought you'd like to know.
In short, this creeped me out a little bit. But like, in a good way.
