Day 2 of the Drawing Exercise

Day 2 of the drawing exercise I'm doing. Literally been itching to get back to this drawing exercise all day and it's about as fun as it gets for me. All drawings are ultimately made without reference, although I have been looking at the book How to Draw the Marvel Way to gain inspiration for poses. I really feel that filling my sketchbook with drawings like these helps me to think more figuratively when creating artwork. Also, always fun to sketch Doctor Victor Von Doom.
