I picked up two of the limited-run Sandmen that Will had at BC09, and liked them so much I decided to make my own.
The one on the right is Will's, albeit with a more fitting hairpiece for Logan 5. The (messier) Francis 7 on the left is mine, though I think next time I'm going to just use a line of vinyl tape like Will did--easier than masking and painting it, and neater too.
The Dome City background was more of a whim to give them something to pose against, but I've sort of wanted to do a scene like that anyway. Might do it with a wider frame and with an actual scene. I used non-Lego materials in this, particularly the clear styrene rods in the background.
Aside from the Sandman on the right, the DS Guns and bomb timers (the latter used for the Follower/tracker) are BAPs, and the head and hair for Francis 7 are customized. I used trans-clear U-clips and monopods on the tram tubes in the background.
