I think there's your problem. If she's 15-17 years old, she's too tall proportionally. 7 heads high is for a fully developed adult, so I think scaling up the head just a tad would set things right, or maybe shortening the neck (which seems to be on the long side as is). Also perhaps I would suggest shrinking the forehead…
first off, thanks for the good words and crits guys, I really appreciate. the proportions, well now I don't really know what's going on but I though they were ok, she's meant to be quite young (15/17 years old) hence the young face but i'll try to see if I can make it a bit older but I DONT want it to be realistic or like…
