Google Sketchup Yale Model

I have been tasked with making a video for Yale college similar to the 'Sol' music video I did earlier in the week. So far I have created part of the college campus in Google Sketchup which I will later export into 3DS Max. Here is my progress on the model so far. I need to take some reference photography so that I can accurately reproduce the rest of the college as the model so far has been created from memory. I also created some mock up images using the BBC Three logo and Yale logo so that people understand what I'm trying to achieve. So far I'm pretty happy with the model, there is some inaccurate details here and there which I will be able to correct with some reference photography.
