This one's reeaaallly old, like almost 9 years old (freshman year of highschool). It's also the only one that's been framed and shown to other people that aren't family outside the internet.
To make it, I stared at a blank piece of paper for 3 or 4 days trying to decide what to draw in art class. One day I just got mad, grabbed a blue sharpie, and yolo'd. Within 2 hours it was done, only because the sharpie ran out of ink (the buildings in the background faded off as it died)
I slowly became less angry and more patient over the years, and my artstyle/output has changed with it... it sure would be cool to mix the two someday
