Hi,
looks great on details. But might be a unclear with tones and colors. The hand with the sword isn't read so well. I thought in the beginning what hand is not a hand but part of the head. That's might be because these two places of interest are placed to close and with similar tones to it disturb each other.
I would suggest to separate the sword by place and thone. We acrualy have two planes here: head and body and the hand with sword, so marking it by tone should be a good option, maybe make the sword more detailed and contrast because it's closer.
