Do you have a reference photo you're using? It'll be much more helpful for us to critique you. Have you tried lining everything with a REALLY light pencil? I still see evident outlines in the hair and on the chin (which I'm going to assume is because it isn't finished and you want to make it darker?) but uh, yeah, people don't have outlines in real life. I'm sure you already know that.
Are you drawing from a black and white picture? (You seem traditionally old fashioned to do so). That will help you pick out the shades a lot better, but I don't even use this method, so either way is fine. It's just if you can't see it on the cheeks and whatnot. Actually, I wouldn't worry about making the cheeks so prominent, no one really bothers about that. Just get all the main components down and then work on the detail. Go to another area and see if you feel more confident on doing that. I'll just move to a different place if I get frustrated with a picture.
You're attacking detail much to early on in this stage, like the strands of hair. Just make sure you've mapped out the whole picture beforehand and it should turn out fairly well. The hair also needs a few more layers of B pencils. I'm going to assume she has jet black hair?
I'm just rambling here. Hope you take that in. Dx
