Lighting: good use of I like the shadow of the crutch and the angle it is cast against the wall.
Composition: Nice angle - triangulates the frame well
Exposure: seems right on
Subject: lacks interest...it's a crutch. Does not really tell me a story, and the crop is not one that would work well for a stock shot.
I keep hoping for something to emerge from those shadows, like a stick-figure leaning on the crutch, but it isn't happening. It's a competent shot, well lit and nicely enough detailed, but I can't see it as an engaging image.
