Well as an expert on how blood works (slight sarcasm) here's a few tips:
1. Make the blood...splatter a bit more, make more little drops of blood here-and-there, to add a splattering effect.
2. Your blood looks more like someone dipped their hand in blood and smeared it across a wall. Try to take-away the little dots away from the blood texture.
3. Shape is good, practice on how liquids splatter, go outside on the pavement with a bottle-full of water and splash a little water on the DRY pavement. Observe how it splatters, it helps me.
Other than that, a very VERY good first, considering the inner details are very good, just a bit less of the pixel-sized dots.
EDIT: If you make it in a .tga or .dds format, I could make it into an overlay for you, if you would like.
