The fur texture here is pretty good, as is the original pencil sketch. However the last version has the highlights done in such manner that the cheek and side of the head come off as flat - you could try having the highlight on the top of the head reach all the way down to the cheeks to give a better impression of downward light reaching them, to reinforce the 3-dimensional shape of the head.

Also, the collar bone shouldn't reach that far back over the shoulder, but should actually be closer to half its current length. If you trace your own with a finger you can see that it will stay strictly on the front side of your body.

But all-around this is a solid effort, you're certainly improving.

du gjore henne fantastisk og jeg er helt enig med deg:D
