I couldn't stop thinking of a fic I enjoyed recently, "Smiling Flowers"

Its not the grimdark Cheerilee fic you may be thinking of, so don't let the link scare you away. ;)
So I ended up drawing this on an index card! I've been wanting to draw Cheerilee for a while. This took me more than 3 hours. I don't think I've ever finished something this complex in one sitting like this, though. Used micron pens, Prismacolor markers, and pencils for where I was lacking certain colors.
