Nice job, Rae Ann. Looking back, I think what really struck me about this are the highlights (ironic in a shadows challenge), especially the one on the pipe and just below the pipe. It creates this silky(?) otherworldly texture.
sepia is a great choice. great tones. great shapes. great textures. great abstract composition. did I mention this was great? what rhymes with great? 8!!
Subtle, very subtle. I don't know if the sepia works better than straight B&W for this theme..Comp is interesting but the reflection is distracting. Just my humble opinions...
I think you need a bit more contrast between shadow and background. The shadow isn't really the main impact of this photo. My eye is immediatly drawn to the door and the pattern of bricks and then the pipe.
