its all so dragon warrior style
what with being able to see the exterior walls & such
that way... it looks more like a stone house than a dungeon or cave sort of deal

edit: oh
...I guess I was describing the mine tiles you made :P
In which case this was intentional

Oh and something I didnt catch the first time...

It isn't going to repeat very well. You can see in the top section of the example where you have that 64x128 section of wall that there is a very clear seam in the middle. That seem is going to show its ugly head everywhere :X
