#1's a nice shot. It does need to be straightened out though. You can show a grid in photoshop and rotate it.. I don't know exactly what you'd do in other editing programs.
Yeah I think that the vignetting is something I am going to have to learn to cut out. It almost seems like a crutch for me. I think as a newbie, it kinda makes me feel like they look more professional! LOL I don't know why!
