Time Capsule Observational Drawings

I had twenty minutes to put my mind on paper and I had three rubrics of a self portrait, a random object and the corner of a room. This is what I came out with. In the first two pictures the only materials I used were graphite pencil and in the last one I used actual paint and water colors. This process was fairly easy because we already had a prompt to follow so I sketched all of these drawings out on their own piece of paper and then either made the sketch darker for the final product or I painted over the lines with some colorful paint.
