I really like the Port shot of the container cranes. They seem a little soft on my screen and I would like those towards the rear to pop out a bit more. I think that brightening the rear ones a bit would make the repeating, receding pattern pull the viewer into the frame which would counter the effect of the booms all pointing skyward and to the right.
I am too lazy to do my Google Maps street detective work to find your tripod location for the first one. I do like shots with the Manderin Oriental tower since my wife and I stayed there in 1993 on our honeymoon. Well, after I typed that first sentence a few minutes ago I challenged myself. It looks like you are on Montgomery St at the top of the stairs between Green and Montague Pl?
