Allright, I have an example work uploaded to Filesend. It's a pyramid dungeon, three levels, with an explosive finale at the bottom.
This took around six hours total to put together, and despite not having the finishing touches put on it (I started getting crosseyed from all the sandstone XD), I'm rather proud of my work.
