I personally prefer the stone surrounds you have just done (my favourite being the first of the two). I hesitate to say this because it is such a great composition but in the first one with the bricks it sort of feels like the bricks are the wrong way round (IE vertically laid rather than horizontally).
However as I said this is a great, stunning image!
Nice variation Chris!
I like the first new one more.
Now its time for a post-apocalyptic hall scene with eerie light!
