cliche but just go for it and practice until it feels natural to get the shape you want would be my advice. just focus on pulling stray hairs that aren't in the thicker arch part of your brow and you will work towards a natural femme (or just a cleaner) shape. i don't go for the super femme either just clean up the stray hairs. there is videos on how to use geometry and shit to do it the "right" way but i got good at it by vibes based practice and it takes a surprisingly short time to gain confidence. you just have to go for it, the worst case is you overpluck them a bit and they grow back very fast anyway
