Hey Nick, I commented and tried to critique a bit. I am not wise to the how-to of pictures, I only know how I like to see them presented. Good stuff though!
I do suggest maybe framing them in a image program to make them look more professional, but sometimes the framing does take away from a piece. As well, don't let the dimentions of your camera control you. Cropping can really bring out aspects of your pictures that you didn't know was there.
Hope I help a little and that I don't type like a bitch.
