looks nice :), though somehow it seems unfinished to me. maybe it's that the hair looks slightly "sketchy" to me. also, the side of her face seems unusally "wide" to me, feels strange. shouldn't at least a bit of her ear be showing?
Great! Think this portrait would look more better on a shaded background :)
The alternating hatching directions are a really cool effect! The texturing on the hair is also super quality.
love the style. 
amazing work.
but... is just the style or there are many jaggies under her mouth?.
Well done but I think that there is too much horizontal space between the eye on the left and the beginning of the hairs...
I roughly made this edit to show what I mean:
