Ok, I must have lied. I can't believe I had forgotten all about a piece I was working on. I definitely think this could be considered a swarm.
An interesting way to go about illustrating is letting chance take the wheel. I was stuck one day, so I just started spattering tea on a piece of paper. I didn't know what to do with it afterward, until a week or two later when I noticed they kind of looked like jellyfish. And that's that. Most of the time when I get to drawing, I never know what I am going to come up with. It's always a surprise.
