I've scrolled through the portfolio. I don't think there is anything i can say about the art itself, it's just awesome.
I like the way you kept the whole thing simple, clean and easy to look at and still understandable what is what!
I watched a podcast on portfolio tips that i would recomend to everyone who wants to submit a portfolio at some time-some stuff i didn't even think about and they really make sence. But instead of thinking about them on your own, let someone who knows, tell you;)
It is longer than i remember but i still think it's worth listening:)
