I spent around 2 hours or so painting up the 20 bases and can finally say I am finished with them. Still need to paint the sides a solid black but the rest of it is finished. They are pretty straight forward as far as painting goes:

Primed black, drybrushed with vallejo model color dark grey, drybrushed with vallejo model color london grey, washed a touch with vallejo model color smoke, and finally drybrushed with vallejo game color wolf grey.

The bronze bitz were given a wash of vallejo verdegris. The iron poles for the razor wire were based with vallejo air brush color hull red and then lightened with both vallejo game color terracotta and vallejo model color red leather.

Here are some pics:
