Photography Homework: Window Light

Last week in my photography class, we were learning about using window light. Because I didn't have any willing subjects this morning, I improvised with a couple of different stills. Our assignement was to have the subject facing you, have the subject face the light, and try to get a couple different expressions. Working with what I had, here is what I shot:
 
 1/320s, f/5.6 at 40.0mm iso100
 
 1/320s, f/5.6 at 46.0mm iso100
 
 1/320s, f/5.6 at 24.0mm iso100
 
 1/320s, f/5.6 at 36.0mm iso100
 
 1/200s, f/7.1 at 55.0mm iso100
 

And here is my first attempt at a Photoshop Elements edit. Not really sure what I was doing (layers?), so I need to spend some time learning what I can do in this program.

Stay tuned, because I was able to use live subjects tonight with window light on the opposite side of the house. :o)
