The animation was well done for having been done in PS, I know there are other programs that are made for animation. That said though I feel that on the whole the animation was a little choppy. It would really look professional if the moving visuals were just extremely smooth. I dunno if it's the limitations of Photoshop or something but they would look nicer with more frames for movement. The vector portrait at the end (was that of you?) was a little off, it was hard to tell what it was at first. The splatter brush transition at :54 seemed unnecessary as well. I'm not sure why but splatter brush + industrial design seem incongruous. :/ I could be wrong!
The music didn't seem to fit. It was a little too... Sorry, I can't think of the right word. It was a little too upbeat I think. Something more subtle would be less distracting and allow the audience to focus more on the work you're presenting. Maybe a simple, repetitive piano riff? I don't know. I don't know if you planned to make your own music or not.
Your work is great though, and that's the important part. That sketchbook hand-drawn look is really nice, and a lot of your designs were unique and innovative. "Rocking chair" really stood out, great design and play on words. The presentation just has some rough edges, but since it's a teaser that probably means you can iron out some issues before sending it off to anyone if necessary.
Really great portfolio, beats mine by a longshot.
Hope that helped.
