Blood on her fingers

Okay! Seeing this artwork was submitted to our critique folder, I'll be delighted to list my opinions:
As far as I see it, this work displays a brilliant use of colours, that blends excellently together. I love how you have kept the woman's pose so simple yet express so much trough her pose. ^^
The only thing that really puts me off is that I feel her upper body is bent more than the lower; considering the angle, I would have liked to see more of a curve to her spine, as her waist going inwards on both sides suggest the torso is seen from front. 
Another thing would be based on the tittle; seeing it mentions blood as an important factor, yet it blends as much as the other colours. If you wanted blood to stand out more, you could mix it a darker shade. However the later is only speculations, as you might also have wanted the blood to be a part of the many shades. 
Overall, the picture comes out great though, and I really like your work with the water colours.
