First time in a studio

I attended a photo class at a local studio today and got to shoot with a model for the first time.
The Pro had never heard of Sigma or Foveon except for lenses of course.

A very pleasant guy but due to the number of people attending I only got a few shots in.

Here is a selection all with SD14, the first 6 are with the 50mm F2.8 EX Macro and the last 3 are with the 24-70mm F2.8 EX, it is the older full frame non Macro version, this is my favourite lens, heavy but really sharp.

Constructive criticism alway's welcome
