I feel like it needs more, maybe some feathers or a bigger bow or something. Or should I keep it simple?

Feathers with the bow might be a bit much, it reminds me of Katniss from PalWorld lol

Just tilted oppostie

Simple for sure. If you texture the band/ribbon with a pattern, like, say, polka dots, that will be plenty decorative!

i think it's perfect like this!

Ok I'll do some fancy stuff on a different hat, maybe one with a simpler crown
