I generally like it, not bad at all, however I would say the head is a bit off, have you tried looking at it in the mirror or turning the page? that would help you find the mistakes. You might wanna also check the chest. Specifically I feel like the alignment of the eyes, the general shape of the back head and mouth need to be redrawn. The pose is a bit different but i like it, I also really like the shadows, especially in the bottom part
