Are those the Dwarven Forge tiles? They look great!
I have a huge box of those myself. They work all right, but the outside tiles are less than 1" square due to the walls, which is a bit of a pain. To be honest, they look nice, but I find they don't work as good as they look.
Yes, Dwarven Forge come fully painted and have many many sets. They are very very pricey too but it is a collection done over time. When I had some I just played the half squares equals a full and worked ok. Dwarvenforge.com is an awesome site with a great forum.
10/10 for creativity
Fabulous.
