The flavor text for my entry...
Minis used were:
50090: Townsfolk: Jock, Chick, Nerd
50027: Captain Griffon, Superhero
50056: Carmine Defazio, Mob Hitman
50012: Jack the Ripper
The bursting floor and Captain Griffon are where this whole thing started. I had one of those GW basing kits that came with some mini slate chunks and I thought they would look perfect for busting concrete, though my first impulse was to have someone being hurled into a sidewalk, shattering it, and the hero hovering over them. When I went to Hobbytown to pick up the hero, his villain, and his damsel in distress, the villain I wanted was gone, I couldn't find a suitable damsel, all the minis I used were on sale, and the whole diorama sprang fully formed into my mind. I got everything in the diorama for just twenty five bucks, including the plasticard.
Captain Griffon/Strong-Man is clearly squaring off with someone in that stance and he reminded me of a panel in Alex Ross's Kingdom Come comic where Superman, having flown through the planet's core to get across the world because it was quicker than flying around, busts up through the floor of the Batcave with all these chunks of stone and blobs of magma flying out as shrapnel. I just clipped his base and bent his feet down to make it look like he's flying and it worked almost perfectly. I initially tried translucent rods, but they frosted over when I hit the whole thing with Matte so I just painted them a neutral grey.
Originally I was going to paint green and magenta footsteps and puddles all around the floor to show the path of the "PaintMinions" as they walked around the museum and Art's paintbrush and smears were going to be rainbow colored, but I ran out of time to keep embellishing my entry. The marks on the masterworks are smears of their own "Anamorphic Acrylics" and not Moderne's much more dangerous "Acidic Acrylics", though their Paintball Tommyguns are loaded with acidic acrylic paintballs.
Did I paint the art reproductions? Yes: If by "Paint" you mean "Find a bunch of classic art online and then print them off on my roommates professional printshop quality color laserjet and glue them to little plasticard picture frames." I did paint on the smears, though!
