Drawing and painting with actual paints is something I don't do very often, so in all honestly any 'technique' of mine is really just a series of trial and error. X3 Some work out, some don't. I'm pleased with this effect, though, it did come close to what I had hoped for. ^^d
I'll probably take up more traditional painting up ahead - we're moving to a bigger place, and I'll finally get to have a proper workspace (sans cats getting in the paint). So playing around with fun techniques will likely be fun.
