I like it. It's trendy and kitschy, your use of color and texture is great. The hardest things to model are humans, and it was kind of apparent that you took a shortcut, but it was still cute, and definitely still amazing for the timeframe and artistic/aesthetic creativity! The Prius commercial was also great--I liked the merging of textures like in an imaginary universe and the changes of axis. It was a bit barebones though, like too much time was spent on each little vignette. Still, as a proof of concept for commercial video creation, rather than literal marketing, it was an excellent show. Hit up some marketing classes. 🙂
Also, Prius isn't exactly natural unless you have $20k of Li-Ion battery upgrades for a plug-in system, tires not made from petroleum, synthetic oil that gets 100% recycled, and it was somehow manufactured using all renewable, sustainable energy like wind, water, or solar power--and I'm guessing you don't. 😉
