Though very nice, perhaps a bit self-indulgent.

Constructive criticism: Agreeing with PJZ99 the Depth Of Field / Blur effect is used so often that it loses its appeal and impact. Perhaps OK as an exercise for overkill for a presentation.

Clearly not Firefly. In order of opinionated preference, I'd say: VRay, Maxwell or mental ray and lots of rendering time to boot. As a PRman fan boy, I appreciate how much easier it can be to achieve this look with other renderers. - most of the lighting is so soft and it looks amazing. Don't want to imagine how long this took to render.

I hope I'm not the only one that thinks that 12 minutes is a bit long. Perhaps broken up into several three minute segments could be more effective? Honestly, if you're trying to get hired, do you really think a company will give you 12 minutes to prove your worth? I'm gonna say no.
