wooouw pretty nice ! The only thing a bit blurry for me is when you talk about a large lineart and absolute pixel, can you enlighten me on this please ?
Otherwise I really like your art, it looks really nice, if I may add a few feedbacks though, you might try to put more volume informations into your armor pieces (the kunai especially look flat)
And also add some more storytelling to your composition, You managed to guide te eye pretty well (I think) but I don't really understand what she is doing =)
Other than that, great job, I can't get such a nice line so well done there =)) Cheers !
