So I realize this isn't what the "normal" sketcher daydreams about, and it's not like I'm always a total geek, but if there's anything that I can get lost in thought with, it would be thinking about the physics behind everyday experiences.
I decided to use pen which I have never done before and I'm pretty happy with how it turned out. It brought a much more dynamic feel to the picture and it forced me to just go for it and adapt as "mistakes" were made.
