urgent help..

thanks in advance to anyone who comments this before my interview and portfolio review..
i have my review next week.. and so far ive only got about 10 things to put in my portfolio, and im not too sure whether itll be enough..
can anyone give me ideas about what else to put in..
so far ive got:
life drawings
photos of my final pieces (because theyre too big to take)
and just a few random bits like edited photos etc
the course is just a general art foundation so it covers all aspects of art?
any ideas?
and also if anyone has had a review/interview for art foundation can you give me some advice on what they liked about your portfolio etc, itll be much appreciated!
thank you! xxx
