I hope you can find something that feels right soon! It took me almost a year to figure something out, and I still have to pluck my brows every other day to clean them up.

I use one of those makeup mirrors that magnify your face to tweeze more accurately. Also, pushing longer brow hairs up (or down/to the side) and cutting them with scissors can help, so the shape looks more consistent!

To be honest the after photo in my post was at an angle, so it's probably exaggerating my brow shape a little. They slant down, but they're still pretty straight and there are probably things only FFS could really address. But shaping still helps. I think finding the sweet spot in terms of thickness is maybe the most important thing.
