Alright, now I know what to crit

I think the proportions are off on her face, perhaps not against usual anatomical refs but compared to who she's supposed to resemble her face seems too narrow and the distances between the various parts are off. I've just played around with that render and the closest match for angle I could find and it does seem a bit off, I'll send you some more pics to work off. I could be wrong and it could be the angle/lack of hair throwing me, but it never hurt to be sure.

Also, try avoid anything too muscly... she shouldn't look like an athlete, but nor should she look like she's been to McDonald's every day of the week. Try find the middle ground, something that would fit a fairly young and fit person but not one who goes out of their way to look the part.

Uploading shit, expect a PM soon
