Fons: I am not sure if you want my comments or not. So I will give it another try: In #75 the orange heater cover is the strongest color element and distracts my view from the fine instrument & player. I also wish to see the hands of the player and the valves. All of this together make me thing that ypu should habve take the shot from the opposite direction.
For me photography is hardly a documentary thing, it is contrast, the peculiar within the ordinary, beyond concept, the futility of mans' judgmental projections and all that, thanks for the commenting Frank, that's a sign of life for me, after all we are human.
