This class is really fun! I'm learning a lot already about how to use my abstract side of my mind more (something of a weakness for me). I think I recall doing something similar when I was a little kid... I remember swiping random pencil lines on my paper and then going back to draw a figure out of it. Although they were really ugly, it proves that we become less creative and flexible with age if we allow ourselves to throw away a certain way of thinking/seeing in order to pursue rationality and order.
For me, this assignment was really hard only because I'm much too literal... so to avoid representational silhouettes I had to draw with my left hand and even look away as I stabbed my pen all over the tablet...
The assignment: Make abstract blob/marks in silhouette and go back later and sketch in some rough characters that you see in the silhouettes. This makes room for more flowing shapes rather than drawing a character from nothing and darkening them later... that can be really stiff based on personal experience for other assignments (character turnaround sheets).
Will Add the refined ones later....
