This is a wonderfully understated shot. The outside silver and blues against the inside golden warmth. As for cropping, I cannot find anything that does not contribute to all the musings that this photo provokes.
This is an interesting shot. I am glad you left the colour in ... I love the blues between the umbrella and the wall I also love the turned up section of the umbrella ... good work here
Cropping is your friend. The right part of this image doesn't add to the overall feel of the shot. The writing on the wall to the right pulls my eye away from the man at the table. A square crop that removes that will keep me looking at him and the people behind him and engage me more. Toning and exposure are good.
Kinda looks like Marac. Love the blues of this, with that touch of warmth coming from the window. Excellent location, nicely composed and exposed shot. Like the girl (I think it's a girl) with the nifty hat at the next table, too.
