Ummm...yeah, I stumbled upon this and I was like, OMG, let's some blood in the background! Cnc please!
You could do much more with this sig. :3 If you stop with it like it is now, the girl will stand out too much compared to the background. That is a risk with the anime art, sometimes the shading style is very simple and to the point. You should add more shades on her yourself, like a reflecting effect caused by the background. If you want the blood to have the same colour, darken it more - blood's close to become a red-brown tone in real life.
okay, this is seriously a tough one, but I redid it and darken the blood a bit. if it's still not good enough, I use photoshop so if someone could help me with that, that would be great Cnc!
