It looks a lot like she's made out of silver. She looks an awful like those performance artists who paint themselves in silver. It's a great thing if that's the effect you wanted, but if it wasn't, then you need to work on making your values darker. Her hair doesn't really look fake to me, it's just that towards the end it should be thicker, because it looks like she's sporting a mighty weird hairstyle to me. (The dark shading looks like the background to me.)

The eyebrow looks to be made up of mostly vertical strokes, which makes it look kind of fuzzy. I also think that the eyelashes should be thicker and slightly longer. A more detailed background will also make her pop out a bit more, right now it's just dark and blurry. (Not super detailed, but a bit more than you did here.)

You mentioned the jawline, so I won't touch upon it.

That said, for one of your first portraits, you captured her very well. The shading is very well, and you rendered the majority of her features very well. It's quite good.

me agrado mucho los efectos de luz en las diferentes texturas como la piel y el pelo me gusto

The background was really blurred in the original picture, a fake setting. That's about it. For the rest, I really appreciate your criticism; thank you soo much for taking the time and patience to inspect the drawing! I will continue to improve my portraiture... again, thank youu!!

The hair is beautiful. The stranding and texturing make it look absolutely real. I can only imagine the time you must have spent on making it look so authentic. Maybe a little more detail around the eye and eyebrow, but that's only an idea.
