Invite help - appeasing Groomzilla!

I was super excited bc I got one of my initial Tessa proofs and I really liked it – but now Groomzilla is making me have second thoughts. He says he likes it, but that with the dragonfly and all the colors it doesn’t seem “formal” enough. But that’s why I like her designs!

Any suggestions on how to make it look 'less like a party invite'? Should I take off the dragonfly? But what would I put in it's place?

The one thing I’m changing is to have my mom and dad on a separate line since they’re divorced, unless someone has a better suggestion for that too.
