Hmm... not sure if the hand are too small, or if I only think they are too small because it as been said so much already... it doesn't seem "ridiculously" of proportion for sure... she could strangle herself, or cover half her face, so it seems quite legit. Same with the wast, it seems more like a body type variation than a disproportion to me... If I wanted to be very nit-picky I'd say the sword blade seems a little thin or short, but it isn't blattantly off either.
On a completely different note, the rendering and color choice make it even MORE awesome than the original image suggest... Great job! ^^
i agree that the hands are to small and the waist is a bit too big or hips too small and she sorta looks like shes suffering from cameltoe.....and like the guy above its a great choice of colour and i always love your art, please dont get offened i was just pointing out what i saw i really do love your art
