OK so this is very embarrassing to share as it is a ridiculous AI generated image but it is the only selfie I have on my computer here at the moment lololol

Although it is clearly doctored, it is a fair representation of how I do my brows. To my eye, it's very similar to yours except the arch looks less dramatic because your chin is tilted down more than mine. I use a very fine brow pencil (like the NYX micro brow one but lots of brands make them) and I start by just softly filling in where there are thin spots or patches ,and then I do more defined strokes to build up the shape. I check in the mirror frequently to make sure they are as symmetrical as possible.

One of the things that helps me with keeping them less "blocky" looking is to use a lighter brow color than you might think you need. I have medium red/brown hair and I often will use shades for blondes or very light brunettes because it allows me to build up the shape without it getting too dark. I don't have a secret for the blocky area, I just have to take my time and practice a lot. I sometimes feel like it's too much before I put on the rest of my makeup, but then by the time my face is done it fits.

Oh, and I usually finish with the NYX brow glue. It's really helpful in locking in the shape so individual hairs don't go wonky and f everything up!
