Robert,
The idea is good but I don't care so much for the execution.
The outline of the woman on the right is obscured by the fussy background. I would have taken a couple of steps to the right and shot them from a point really perpendicular to them rather than at this slant. (Since I don't shoot f*i*l*m I can be profligate with my shots and start shooting from wherever I am until I get to the best spot.. That way, no matter when the arrangement disappears, I have something)
Also I understand that people eat lunch when the sun is high but the shadows are blocked up and that doesn't help anything.
