A couple more tips:
* Creating a strong photograph is far less dependent upon what you're shooting with and more about what you're shooting. Instead of spending your cash on a Mark III or a Leica, take a photography crash course at your local photo school (Seattle people: http://pcnw.org) (see: times square and the bread)
* Don't be afraid to strobe your subject in the daytime. For example, in the second photo, I would've tried taking this in three ways: 1. as-is, 2. strobed, and 3. HDR. The background exposure is pretty good, but the flowers in the foreground are underexposed.
* Watch out for stray junk in the foreground. In the bridge photo, I'd crop out the errant flowers at the bottom of the frame (and straighten it).
* If you have a lot of gray sky in your photo, your camera is going to do its best to underexpose the photo. Watch out for it, expose for the foreground, and do post-processing if necessary (see the last photo of the bread).
And, on HDR: "Also, HDR is so 2007, natural photos are where its at."
Sure, shitty, haloed HDR is so 2007. If you do HDR right, though, no one will ever know. Here's my favorite HDR photo I've ever taken: http://www.flickr.com/photos/aaronbrethorst/3266221538/in/se...
