fundamentals of lighting class with Sam Nielson

I jumped on board with Schoolism's kickstarter, and the first class I'm taking is called Fundamentals of Lighting.  Sam Nielson works for Disney's Avalanche Studio, and so far I'm loving his class.

lesson one was really basic, which is exactly what I need.

here is my completed assignment.  I know that I did this one too dark, and there isn't enough contrast.  I could have played with the level adjustments, but I felt like that was cheating?

anyway, the bottom right image is the image before placing textures.  I have a lot to learn, haha.

edit:  I decided to tweak the lighting anyway, and I think it looks a lot better.
