Do you have any photos of your work? It's always nice to include some photos to tie together the other elements of a portfolio, especially when you're trying to convey the transition from process (notes, character analysis, etc.) into product (photos, reviews, etc.).
"We don't value the lily less for not being made of flint and built to last. Life's bounty is in it's flow, later is too late. Where is the song when it's been sung, the dance when it's been danced? It's only we humans who want to own the future too."
- Tom Stoppard, Shipwreck
