Wow, nice write up, thanks a lot!
I was thinking about it a fair bit more today, and I think I'm going to do a 2 minute video, showcasing 5-6 models (20-24 seconds per model), and including a link in the description of the video (it would probably be on Youtube) to a PhotoBucket album of wireframe renders, and things like that of the models in the video as well as UV maps, ect.
The video would have maybe turntables of 4-5 cars (the company I'm doing this particular one for only does driving simulation and racing games) and 1-2 fly-bys/walkarounds of track props (pit lane garages, tyre stacks, etc)
For the turntables, I'm thinking one spin around showing it tectured and all, then another wire frame rendered.
The job only entails modeling and UV mapping, maybe texturing depending on the situation, so I can't think of much else to show... Any more suggestions?
