Studio Studies, pt. 1

Recently, I've been trying my hand at shooting studio nudes. Being a (returning) college student, I get a great deal at a local studio, and I've had a few friends brave enough to step up and allow me to photograph them, sans clothing. A few weeks ago, I had two friends stand in for a test run so I could get my bearings with lighting, placement, time needed, etc. Then, this past weekend, I had a larger group of friends come in for a much longer shoot.
A few results from the first shoot are below, behind the cut.
I won't see the results from yesterday's project until later in the week, if not the coming weekend.
