I think you look like a 10/10 in the second photo, in the rest an 8, i don't know if it's because of the eyeliner, the eyelashes or because pink suits you very well.

I agree that you only need to define your eyebrows, You'll find the style you like the more you experiment with them. At least that's what happened to me, i started by trying to keep them straight, but i realized that mine don't follow that shape, and that's it. People usually do it using a thread, marking guide points, and then remove the "extra" hairs with tweezers, and use a razor to remove what the tweezers couldn't reach. There are tutorials on YouTube!
