>>1761966Lines look fine to me, hair tips are fine.
Things I dislike are the puke green leggings, I think they should be orange to go with the fall-ish colors but you can try what you like.
I also think this image looks better when you add a darker outline to the full image, all I did in Photoshop is add a stroke to the image scaled it till the image "popped" a little, tips are rounded because of using strokes in photoshop but you get the picture.
Image is also a hair desaturated on my monitor as well but that can easily be a preference thing.
