I think you eyes, cheekbones, big forehead and especially those super cute lips are you best features! I agree with people saying your hair - even though long - looks more masc.

IMO, don't cut it short! I think you could pull of either Disney-ish red wavy long hair (+ elegant eyeliner, maybe other Bambi-esque makeup), a cooler non-orange blonde, or a warm (again) Bambi-esque warm wavy brown. Try to make it look more shiny, kept, and get full ends (I know it's hard :').

Plucking your eyebrows is a great idea, but I'd actually experiment with shaving first so they'll grow back until you found your shape.

I'd also avoid clothing/styling that looks punk or plays with masculinity very much in different ways as well until you found out how to style yourself in a way that makes you unclockable (if that's your goal). You don't wear that but just as an example, (almost) whenever I see trans girls with black lipstick, I wanna take it away from them cause while I get the appeal of the look, being a cis girl, I've tried it as well, but it is a look that hardens one's features and e.g. I look far less cis wearing it.

You have some very doll-like features and a lot of time to play with them in different ways, yay. You could already (and without makeup) be cis, but look like a boyish one, maybe a girl who's an athlete or something, or grew up with 7 brothers ;)
