Playing with bases!

Some time ago I was playing around with GS casting, now I'm playing around with bases.
Here are some urban styled ones with some nice, in my opinion, brick-work. With a bit of practice you can easily make a lot of these in one day (or in my case night...).

I'm most pleased with the big one, I added some spent shells and a cable to it.

The bases above are in a bit more "battlefield"-fashion.

This last one is crawling with undead. I was thinking about mounting some sort of evil wizard, preist or demon on the rocky part.
