Blood effects wrong in alot of places.
Good movie. The poblem I have with some of your blood effects, is that, in some places (especially when the bodies fall on the floor) the bodies keep bleeding after they have died. The body stops bleeding when your heart stops, it then gradually drains out of the body. When you do headshots, you can have spurting blood for the first few seconds, but only until you think the heart would stop beating. Then you must change the blood effect to "draining". When you die the blood begins to flow to the lower capiliaries of your body (if you are lying face down, the blood flows to your front, and vise-versa) this means that the only amount of blood that can flow from the head would be the amout that can be stored in your head (I'd say about 1-2 pints, max). In most places in this movie, that isn't a problem, but in some, a un-realistic amount of blood leaks out of the head.
Just something to remeber in the future.
Keep it up.
