looks really cool. my advice would be: add more occlusion between the bottom of pillars/walls and floor. Especial the both pillars look a bit floating to me.
I didn't get any pictures, but I'm sure there's something floating around on a cell phone out there. I'm going to bring my camera to the Thursday meetup, though.
There is no reason is has to be a single mesh, floating and intersecting geometry is a very common method of modeling lowpoly objects. The topology could also be changed around like Stromberg said.
Minor Update Still pretty low poly, but I tried to make the tusks look like they were actually protruding from the lower lip/jaw not just "floating" there.
My 1st try on a terrorblade weapon. Maybe you like it, it has only 1 Horn idk if it is a full skull or just a half of one. The underjaw is kinda floating.
Instead of: $StateA = `xform -query -objectSpace -translation pSphere1`; try this so that you have array: float $StateA[] = `xform -query -objectSpace -translation pSphere1`; then the same for $StateB
That booleen modeling is not really going to fly most of the time. I'd highly suggest taking a look at floating geometry like earthquake demonstrated for you, or making a plane and bending it.
