I shot mine a little differently. I didn't use any oil instead I just used some old unmixed paint which I poured into a plastic see-thru container. I then painted using a small brush along the inside wall of the container to get the shapes (partially submerged in the thin unmixed part of the paint). What you see here is a side view of the container.
It reminds me of one of the illustrations depicting the underworld in my childhood copy of C.S Lewis' Prince Caspian. From a top-down perspective I can distinguish a single figure looking back up at me... from a hell I have escaped.
This is a fascinating abstract - hellish, what damnation would look like. I'm not even religious, and this makes me want to pray for forgiveness. :) Seriously emotive.
