i like this one, the grittiness to it, i like the effect you used, and that special Tim angle suits it well. must have been an interesting place to see.
I always look forward to your posts Tim, you're not afraid to do something different from the norm. This is a good example, I like the gritty feel and all the lines. You did well to avoid convergence on this, it's a good shot.
but great photography Tim:)
