Overall it’s a good start. you have all of the elements of a blood impact (spray, trails, decals). So at this point I think you should focus on refining the motion and shape of the overall effect.
I took a clip from the Call of Duty video you listed as a reference.
In this clip the blood is exploding out from the impact point. By comparison your blood is simply moving in the direction of the weapon swing, which I think hurts the forcefulness of the impact.
Also, your effect has a large volume of blood, which doesn’t feel justified to me. So I would reduce the amount of blood.
As a final note your camera angle feels a little awkward, maybe pull the camera closer and lower the camera height.
I look forwards to seeing your progress on it.
