Some really nice shots. The first two were breathtaking. Good on you.

The first dog shot is adorable, because, well, the dog is adorable.

I like the look on the face of the brown and white dog. Very patient and tolerant.

I felt bad for the poor model floating about in a skimpy dress in such cold temps.

You might want to look at the work of Hurrell, black and white and stunning shots of mainly film stars, to get some ideas.
