Your photograph makes me wish I had been there. This man, this place, the light, it's all there.
Unfortunately you missed it. Rusty's comments are on the mark, but I'd say he is being kind about the composition which needed more consideration before you took the photo.
Go back if you can. Look at the blacksmith working and see how the photograph might suggest itself to you before you look through the camera. If going back is not possible, use this image as a mental excercise. Think about how you might have captured the scene better and consider this one that got away.
This is well composed, but having come from 4 generations of blacksmiths, I don't think it quite captured the 'essence' of a blacksmiths shop. I'm not sure if it's the brightness of the scene or the fact that it appears the verticle lines are off some.
