Maybe a flower field..a forest..

the beach?

Hmmmmm

something like the spirit world from the ledgends of korra. It's really pretty and magical!

Maybe a party, some sort of concert since that nice ol show-now :3

Since everyone's saying "maybe", P E R H A P S you could do a simple pastel orange, pink, or yellow backround. You could also put something in the corners. Hearts or something. It would help your adorable character/oc pop out more so everyone could focus on it.
