I think it looks like a nice size for that style of ring on you. It looks less gaudy because it does not have a bunch of side stones. And the bezel gives it a tidy appearance.
If you dig the high crown, go for it! But resizing down might mess with the proportions. I'd say check with a jeweler if it won't affect the bling factor too much. Also, 10x9mm is a decent size, but if it feels too much, trust your gut.
