I originally started this project purely for the sake of practice. I had no intention to turn it into what I now refer to as, "rage studies."

I also took this opportunity to try techniques I had never used before, such as the folded/cola pen.
All of these are the raw sketches created by specific brush pens or cola pens that I made. I only inverted the colors and slightly adjusted the levels in Photoshop.
Below are my personal favorites from this exercise.
