Where do I go from here?

I have changed my idea many times since I came up with it in July. From the start I wanted to work with 16 different materials and techniques. Then it became 8. With changing my concept from (I am pencil) to (I am bones) changed everything. Then, because of time I made it to 4 different materials and phrases (“I am bones” for pencil, “I am muscles” for ink, “I am blood” for color pencil, and “I am skin” for vector”).
