Not counting drying time, this project probably took about an hour or so for me to finish. I like the earth tones here; it's a lot brighter than my first attempt, which is more dungeonesque compared to this outdoor desert arena look. And it looks pretty good with some of my newly painted minis to show it off.
I have one more sheet of styrofoam I plan use for a Wizard map, with its additional megahexes. I'm thinking of a wholly different palatte--maybe with cooler colors for a more magical look, but we'll see.
