What should i do for my art final piece?

Maybe a sculpturfe of a tree, but not just a normal boring one made out of metal or wood, mmaybe make it out of something unusual like, say, hair clips, pen lids, balloons, guitar picks, safety pins, coat hangers, kettles, teapots, exaughst pipes from cars, human hair etc? I'm not sure how a tree would look but i once saw a chandelier make entirely out of paper clips and plastic ball-point pens? Idk maybe that would work?
