This cover is just flat out enjoyable. I am liking the tan and pastel color palette.
This looks like a sitcom sort of comic. If these expressions are any indication of character traits, we have an optimist, a pessimist, and an introvert. They don't choose to spend time together because of these personality differences, so they live together as neighbors or extended family. The background suggests a generic urban setting to me.
Typical gag...
Cap: Hey guys, the circus is in town! When can we go?
Bow: Animal abuse and elephant dung, no thank you.
Glasses: Bring me back some peanuts.
Cap: They have a bearded lady. Come on, Bow. This could be a new fashion trend, and you wouldn't want to miss that.
Bow: I'm surrounded by clowns already.
