The idea and the conversion are great. You needed to tip your camera just a hair to line up the right window edge a little better. (Neither side is lined up.) :)
The lights(?) above each window add interest and I like the shadow from the roof line. The tonal range is quite good. All in all, it's very clean and nicely done.
Arranged like this, in idealised pose and in regular alcoves between 'columns', these torsos suggest Roman statuary. Your title doesn't indicate that you saw it that way, unless you were thinking of gladiators?
Anyway, it's one of the best entries.
