First time shots with a model

I general take pictures of landscape, buildings and that sort of stuff. Apart from when I have attended weddings I very rarely take pictures of people. I was asked if I was intersted going out with 2 colleagues, one of which is an ameteur photographer like myself and the other is a amateur model. I jumped at the chance.
I made lots of mistakes and learnt a lot.
It was a bright sunny evening and although I had brought a flash gun I didn't use it to fill in the shadows.
I took 95% of the shots at maximum aperature.

All but the last image were taken with the DA* 50-135 @ f2.8.The last image is a poorly taken shot with a Tamron 28-75, should have set the camera up properly and retaken it, but I have included it as I do like it.

Anyway comments and critisms please.

The last one is by far the best image. Shame you cut her foot off. Has this endeavour given you the inspiration to want to do more ?

It certainly has and i will cetainly be doing more.

The last image has blown sky and and blur caused by subject movement, it was hastily taken and I should have checked it on camera. It would have been my favourite but for this.

Cheers
