Monika, don't worry. No point looking at other people's stuff, because everyone is different. I also had stuff from different projects, because I haven't done any self initiated work for many months (just no time) and the tutors told me to keep the portfolio as recent as possible. The thing is, the projects forced me to take a certain route to respond to the briefs and it didn't look much like fine art at all, more illustration (collages mainly). I was rejected by Chelsea, but CSM strangely invited me in, so there's always hope that I can defend my working process during the interview.
