I looked at the face first and said "ah, dudely devil" but when I saw the breasticles I said "wait, she's a man, baby, yeah". The foot has a bit of that weird anime big-footedness to it or whatever that style is with the big feet. I can't really make out if the proportions are right cuz the leg blends into the cloak. Since it's a lady devil you could get away with making the head a little bigger (I always draw ladies with slightly bigger heads and slender shoulders to enhance the petite-ness but I do comic book style, shrug) and that would fix the chestal area. And maybe a little long hair or something to suggest more of a feminine feral look...oh and bigger eyes and lips but not anime huge, comic-book big. You might also want to lighten the black around the body to accentuate her form. The style and techniques are good so no problem there, just some things on shape and form that come to my mind.
