In the end, it is a straightforward commercial tape with a little narration and a single "character" voice. No accents, no cartoons. The only odd thing is the inclusion of a poem at the end because I have already been hired to read poems, so it seemed a strange necessity--a bit of originality and differentiation. Plus it's at the end, where most prospective employers won't even hear it.
It will remain linked at the side. If/when I do a webpage--which seems more likely with my nice new Dreamweaver books and the practice I'm getting at work--it will be there as well.
