This is a really cool concept. You have constructed this very well, I like how the paper is askew. I also think this is a very original work. Sure, there are a lot of drawings of drawings, but this is showing the process to drawing a portrait indicated in the construction of your face. It's honestly a really neat little idea. Your technique is awesome. I love that it isn't all the same- on your hand holding the pencil, it's very smooth and realistic shading, whereas on the portrait, the hat is cross-hatched, indicating that it is a drawing. Seriously, the way you used two different techniques really emphasizes the line between realistic and drawing. Awesome, awesome job.
