The ocher one took seven years. I sure learned a lot about Jackson Pollock while doing that one. I could have called it "Another Punk Throws Paint" because it's pretty common a thing to do among beginners. (Do you throw paint? I throw paint! Don't tell!) I never could figure out a good name for it. I tried to call it "The Gnostic Revelations of Jack Black" (Old #7, of course) but the actor was just becoming well known about a week after I finished. What the heck. I hereby rename it "Old #7."
The other one, Corridor Head, I started at the same time and finished in about 2 months.
I mixed Varathane Diamond floor finish (extremely tough, completely clear, never yellows) in with my acrylic paints as I painted to give the lustrous translucence of oils. It's similar to generic water-based acrylic gloss medium sold in stores, but cheaper by the gallon. I'm such a chemist. I balled up the photography, too. I ought to re-shoot with my tripod, like I knew I should in the first place.
