Light studies

Hi, all!
This is a small scene I put together to help my students practice different lighting conditions during class. Modeled the architecture and threw in a couple free models (Model Plus Model and Design Connected for the armchair and wood log), a couple models the students do themselves and created a few situations.
What do you guys think? Rendering is taking about 30 minutes.
Cheers!

Those look awesome! my favorite one is the ist one.

I like the third one, if there was a little more accent lighting on the blanket

They are stunning. I wish my materials were even nearly as good as those!

Thanks a lot for the comments, lads!
