Oh, out of curiousity, how long did it take you to render those scenes? what kind of hardware setup did you use?
It depends... most of it was rendered on my PC that I built around mid-2010, when the model was finished up. It's an AMD Phenom II hex-core 1090T, which does pretty well. I've also got 8GB of RAM in there, with a couple of GeForce 9800GTs.
I was doing all of this with Blender 2.45, too, which renders a little slower than the newer versions. The still pictures only take about 5-10 minutes to render out, but then I do all of the compositing and effects in Photoshop for about 3-5 hours.
The videos take longer, of course... for a 30 second clip it was taking around 3-4 hours at 720p. I would then take all of that into After Effects, and add flares and things, taking another 2-3 hours.
