Lovely, fascinating, involving composition. A touch too far on the sharpening perhaps? That always shows particularly strongly on diagonal lines, of course - especially in that image right little section between the frosted glass areas of the first doors. Really like the subsidiary, image-within-image work here, the difficulty of finding a route through the chaos of reflections to the 'real' - a neat critique of the corporate world, in its way.
Interesting composition. I like the diagonals but it helps to disorient the viewer and leaves me confused as to which way is up or exactly what I am trying to decipher.
