I like that he used 1.5 inch floor tiles instead of 1 inch floor tiles in the corridors. It looks to make a lot of room for bigger monster figures. Which means higher walls could be built and still allow easy movement of figures. I like the visual effect of having higher walls.
It's definitely a dramatic scale!
I know what you're saying, Mortis, about Hirst sets, but his paint work is certainly better than some, and he's not frightened of the brighter shades of of the HQ tile.
