Cool, it looks like a tileset like you said, it would be pretty cool to have that :D

Looks like Oblivion, but it's not Minecraft. Normal-mapping (or possibly modeling) on the ground, light rays from above, and the lava isn't tiling nearly as much as Minecraft's lava does. The obvious conclusion would be this is a render from some other engine (again, Gamebryo/Oblivion is my guess) with the Minecraft HUD pasted over it.

Still real good work though.
