RB, how about a rose-colored base?
Since this guy is showing some leg, I felt he needed to look like he was actually standing in a hole or something to make sense of the stubby things, so I'm making the base look like he just clawed out of a hole in the ground. Going to celluclay and paper mache over the foam and wood to make it look a bit like turned up earth. There will also be drain holes in the center to allow any trapped rain water to escape as well.
