I really liked the first and third pics -- excellent compositions and color. The second one looked too busy. You might be able to improve it by cropping it.
That's what you get with the trash bag thing they call the EMP. lol
I like the first one using the reflections off the metalic sides of EMP. For me and the artsy feel of the area there I think using a slower shutter speed and having the monorail blurred could have worked with that particular composition. the third is a bit underexposed for my taste losing details in the underside of the Space Needle.
