It aint that bad
I think you're doing pretty well since you're still getting used to the drawing tablet. And i definetly see some improvement when comparing it to your older ones.
The proportions of the face are much better now, and you're really getting better at drawing the hair.
But here comes the beef:
Like the ones said before me: the arms are done pretty bad, they're way too skinny (I wanna see some meat on those bones XD).
And it doesn't really look like she's got any shoulders, it's like her arms are directly attached to her neck. You might wanna get into that pose yourself in front of a mirror and use your own shoulder as an example, a real human body is always a pretty good guide, even when drawing manga style.
And you kinda messed up on the armpitts, they're just single lines (i think you should have added a little more detail) and you placed them too high, and once again: the best example is the real human body.
And most important (to me), the torso lookend really stretched out, you might wanna draw that part a bit shorter, and think you should have drawn the hourglass shape of her waist more clearly, but that's the tricky part when drawing girls. Dudes are much easier to draw :p
But you definetly have potential, keep on practicing.
