So you people can see where I'm at, here's a portrait I did today:

I'm having a lot of issues drawing "real" looking hair. I just have no clue how, especially her's, since they are all "stringy" and I can't think of any better way other than drawing lines with my pencil, which didn't turn out so good...
Also I have issues with the nose and lips, since I never understood most tutorials about them. One instructed me to draw a lot of circles, another suggested drawing "bird" lines, ugh... I just eyeballed them, so they aren't proportionally correct.
Then I have a large problem with symmetry. I was careful drawing the right eye (her right, left while looking at her), and I think I got it pretty good, though it's not that good at all. But when it comes to eyes (and faces, noses, and mouths) when I finish drawing one side, I always struggle with the other side. It either looks awkward or mismatched or whatever. So the left eye came out terrible.
And I didn't really know how to draw eyebrows, I just made random strokes...
And I have a big problem with blending too. How do they do that? :/ I used a tortillon this time instead of my fingers, too...
Here's the model/photographer:
