Ha! No worries, there are a few spelling mistakes in mine as well. It just stood out to me as it just happened to be my paper. I'm surprised you could use images without any sort of copyright. When I had to turn all of my paperwork in, I had to turn in any copyright information for images that weren't mine, which I avoided since I didn't want to mess around with contacting companies. Images were to be treated as research when it came to citations.
Personally, I think physically based rendering is where it is headed for real time as shown by the upcoming UE4 and the update to CryEngine3.
