Actually the POV is from the outside and the large tiles are the courtyard plaza pavers hence their size. Also I have no control over the squareness of the wall bricks as that's the way they are on the image map I made the wall from.  Maybe I should be looking at this as the inside...t'would solve some problems...now to figure out a vaulted ceiling...thanks for the input folks.. ...

 

Once in a while I look around,
I see a sound
and try to write it down
Sometimes they come out very soft
Tinkling light sound
The Sun comes up again
