I like it, Boris. Specifically, I like the repeated circular form of the umbrella and it's shadow. I think I like the second person in the photo because it repeats the form (vertical line) of the first person.
>>>Does it work? I wonder whether the umbrella is popping out enough? Not quite. But, printed in black and white, this might be an excellent starting point for a hand tint. Or, if your darkroom is digital, use layers to render everything but the umbrella in monochrome, then punch up the saturation. Have fun, man. Chris L.
