Biggest complaint is the fingernails. The way you have it now makes it too blunt, and as if the fingernail is going into the finger line. You need to draw the nail as its own separate shape that goes above the finger, instead of going into it.
Other complaint is general endpoint thickness. I drew a couple random lines that had really thick end points. Make the single node endpoints much thinner. The fatter the end points are, the more blotchy and messy it looks. A thinner line that thins out looks cleaner.
For the eyes, try to have some kind of undereye for the eye to go into, even if it is not in the original. The stroke just suddenly having sharp corners on the bottom and being part of one whole eye shape looks out of place, and makes the shape of the eye look more unrealistic.
For the blush lines, always make those with fills. Again, the thin endpoints will look nicer and cleaner. You also want the two separate blush line objects to be similar in thickness. Since I didn't have the original, I didn't know how it was supposed to look, so I just showed how they would look as fills.
The hair is alright, but is too poor from the original to really bother fixing some of the areas.
As for thickness, everything is a lot closer. There are still a good deal of thickness issues on the sweater, but it is an improvement nonetheless. Just keep doing more of them (another 7-8) and those errors will go away naturally.
