What can I say. :thumbup::thumbup: Well done.
But you know me . What is this in the right lower corner ? First I thought is your logo, but no... Do you really need this ?
This looks like it was shot on a stage in a theater. I don't know if that's good or bad, it's just the feeling I get from it.
I think I don't really like it. The frame feels out of balance, with all the dead space upper right, and I don't see a good reason for that. The shadow is nice, but it does not jump out at me. To you, the photographer, it's very obvious and interesting because it's what you saw and wanted to photograph. To me, it's a secondary element, and too far subordinated to the bright contrasts of the gondolier himself to really be clear. You might be able to bring the shadow forward and the gondolier down a bit, and that might help. Might not.
