Drawing blood for sprite

What kind of blood animation do you want? As if its being shot and there's small splash damage, or if hit with an explosion, and there's blood everywhere? or as if its being killed by a virus and slowly bleeding?

If its a small splash damage, from what angle is the shot coming?

I realy can't be more informative 

You could make it sort of like the death sprites in this game.
