Animation Mentor class 4 week 6

I did some changes to the shot according to the mentor's notes and rendered it. There are some stuff I still need to fix like drifty parts and some pops but I'm not going to work on them now. Maybe I'll do that on the last week of this term.
Last term I studied mental ray on Maya 2008 and I thought I got it pretty well but for this term I'm using Maya 2009 and it seems like some stuff in Mental Ray changed and on top of that I had to render a museum and didn't want it to have any windows, only spot and ceiling lights.. welll.. needless to say.. that's not my strongest side.. yet! :)
