I would suggest making your portfolio representative of you and your work FIRST! Stop thinking about what will be accepted, and start thinking about you. People might love what you do, but if they don't like you, they will most likely not employ you.
Make something that is going to display you and your creative style... if you do, "they" won't be the only ones who are happy... you will be too.
