These two fellows are coursers, antagonists from the Fallout universe. These guys were cast in translucent resin to suggest they're using Stealth Boys--Fallout's cloaking technology--to be invisible.
I painted the bases, of course, but I asked some friends if I should do anything more to the figures themselves. There were some excellent suggestions, and I actually tried a light ink wash to bring out some details--but I quickly rinsed it off, preferring the original look. The ink wash just muddied the waters, as it were, and I was too lazy to try the other suggestion I really liked--adding little footprints to the bases.
