Design 21: Social Design Network

It completely depends on the purpose of the art piece you are a making. We normally refer graphic design to commercial design or communication design which serves a purpose or goal. So lets not mix art and graphic design together. If your teacher is talking about graphic design in specific then yes there is a great level of objectivity involved whereas on the other hand if its about art without a purpose except for fulfilling artists own creative desires then its completely subjective. However I personally believe that an artist should create some balance between subjectivity and objectivity both, otherwise I really don't see any point in wasting natural resources just for the sake of art....its a matter of responsibility.
