If you're a student in a portfolio school, you need to watch this video on creativity-online.com.
Sorry I can't embed it. But I've got to say I agree with a lot of what they say. (Craft is often neglected, junior creatives struggle to create "scaleable" work, a lot of schools turn out a vanilla product, etc.)
You should spend eight minutes watching then, then go back and reassess your book.
I'm curious to know what some of you portfolio school students think about this. Love to hear your comments.
