A few years ago I took part in a friendly little competition which was a figure swap one. Everybody who took part put a single figure into a box and took one out from random (obviously putting back their own). I was fortunate enough to get the chap below and decided to make a scenic base for him to stand on.
It's a mix of bits box bits and styrene all put together in a suitable way. Given a muted colour palette and weathered appropriately it only took a couple of hours from start to finish.
