Brilliant idea on the lava flow in the floor. Looks awesome!

If you ever wanted to redo/extend, you can also trowel on the concrete instead of spray. I've used a pool trowel (long, rounded ends) to make very realistic chiseled rock texture. The trick is to 'pull up' to allow a vacuum-like pressure to move the concrete at multiple tiny elevations. Then just knock it down with a sturdy scraper once dry.
