I'd like to know if my photos are any good. I uploaded these without editing. I'm kind of working on my photoshop skills.
I'd say these shots are successful. the white in the building is a little overexposed but nice shots.
Try to find a middle ground where you have details in both the highlights and shadows. The image isn't too bad, I personally would have framed it a little more to the right. There isn't really too much in the image that acts as a subject, at least the way your framed it.
Try the Highlights & Shadows Tool (in Aperture) or it's equivalent in Photoshop (Shadow/Highlight). Take the original image and turn up the Highlights slider to 1/3 of the way through and be happy
