Prepared for rain as well he should be since his stand-in building has no roof to shelter him from the elements. Whimsical rainbow umbrella against the stark black almost silhouetted gentleman. The sky does not look like inclement weather is on the way and yet with the swirling clouds who can be quite sure? The graffiti on the shell adds a note of whimsy to the summoning wizard whose coat has caught the wind. This invites study as it is not as simple as first appears. I do like it.
It's too bad you didn't position a flash/light source directly in front of the man, firing up into the umbrella. It would have set those colors off so well. I do love the composition.
Well that looks like an awesome place to take photos, but there are a lot of elements in this photo that clash for me, and I see no reason for that. I think the umbrella could have benefited from another light source to give it more color perhaps.
