Need help with my eyebrows. Want to look less angry

I’m not quite sure what’s wrong with my eyebrows or how to try and fix it. I know they’re sisters and not twins; one eyebrow is naturally set higher than the other and it looks a lot worse when I smile. But they also naturally tilt downward. I naturally have kind of a RBF so I feel like my eyebrows make me look more angry along with it. I’m not sure if I should try and grow them out and redo them altogether, but if I were to, how would I better shape them to avoid this? Or is the issue that they are too dark which makes them more prominent?
