Some recent portrait photos. (56K Warning)

I took these a couple of days ago, while just having lunch and going for a walk with my GF. Not a planned shoot or anything but I'm quite happy with them and I think i'm improving a bit. I'd appreciate any critique and advice. I'm really trying to get better at this photography thing, so hopefully you can help me out.
