Following up on Erudi's post! I was hit with a burst of inspiration after seeing what she had done so far, and decided to round out the group by drawing all of the characters she hadn't.

I then started brainstorming what some of the actual sneezes might be like. These are a little rough -- some even incomplete -- but it lead to an interesting train of thought. Perhaps some characters could be building up to a sneeze, others in the middle of a release, and some post-sneeze while others just simply watch?
I think showing all different stages of it beyond just everyone releasing at once would be a fun direction to take it. There's a lot of comedy and variety in a sneeze that can be displayed between this group of characters that would help to keep the piece visually interesting.

(that's Blue Moon and Spring Constant up top, with Smiles, Grapefoot, and Darrin next to them. and below are Gusty Breeze, Soda, Anchor Kwill, and Raine)
Whether you guys decide to use any of these or not, I hope you enjoy!
Holy hell, how did I not notice this til now.

These look amazing! And thank you for drawing Gusty!
