Groucho, I'm with John. I'm not too sure what you were trying to do with #2. From the looks of it it's a tiny crop from part of a much larger file. The noise overwhelms it. I think I understand what you were trying to do in #3, but I don't think it quite came off. To me there's too much heaviness in the lower diagonal. The silhouettes are good, but they're overwhelmed by the dock. On the other hand, I can see arguments on the other side of that coin. As usual, the photographer gets to make the final decision.
But #1 is excellent, and, as John said, the guy looks like a mime. His dress is unusual, but possibly not for the location where you made the shot. Good work!
