I didn't originally do this popcorn as an EDM challenge but just to make myself draw something before I went to bed that night. I get tired of not finding time to draw. I drew it with a regular pencil and went to bed. (It seems silly but I was too tired to even draw the third piece of popcorn I'd tossed on my table). In the morning I decided to add some color so I just went over the pencil with yellow and blue colored pencils.
I wasn't going to go out of order on the challenges but in this case and perhaps in a few others I will. No sense in being hog tied to a non-rule!
