Hey, thanks for the feedback guys, lots of things to work on!
Bryan - Thanks, I think you’re right, it does seem a bit too much in the profile. Also, now that you pointed out the brow region, I noticed that my “curve out” for the brow happens too high on the forehead…
VABG - Thanks! Yeah, I think I need to put those subtle wrinkles around the eyes + work on the ones I already have (they are more visible in the high res versions of the refs). Good point about the teeth.
poda - Thanks! Really good point about the eyes being a bit slanted, I was completely missing that.
I think I know what you mean about the jaw - I think it may be the area that I lifted up to make her chin more prominent, I ll see if i can adjust that.
I ll experiment with lengthening the left leg - also I think it maybe that it’s the jeans that aren’t equal in lengths for the legs.
spaceboy412 - Thanks, those are good points! I ll work on teeth. I think i see what you mean for the head - I think it’s a combination of things, like perspective distortion that I used there might be a bit greater than normal, I ll see if narrowing down the front of the face a bit would help further, but as far as the actual head to body ratio, I was actually thinking it pretty close, since she didn’t seem very tall in real life (but I could be wrong there).
I agree about the crotch being over defined. As for the wrinkles in that area, I was actually going for something like this.
As for the wrinkles around the eyes - I found it’s a good idea to exaggerate them a bit, as they tend to get washed out when skin shader is applied. I do need to work on them though.
I agree about the folds on the shirt - not too happy about the ones on the sides for sure, although I m not sure I know how to fix them. I might just redo them from scratch. 
infamouskiller, gpepper - thanks guys.
P.S> I seem to have lost the edit option for my original post.
