Blue Cycle

It's funny how I would normally lose interest rather quickly when drawing lots of abstract patterns like this...but when I'm in school on the other hand...I could go on forever It's really relaxing to draw something like this while listening to lessons.

Since I have nothing better to post (referring to my latest journal...) I just decided to color this school doodle since I spent quite a lot of time on it ahah.
Originally drawn with ink on A5 paper.
