Its a good kill, but the song you chose to go with a 13 sec video could have been better. Also as soon as you kill him that water ripple effect kinda ruins the video because you can't exactly see the kill. Other than that its not too bad.
Instead of the ripple effect, you could have used a slomo effect, and then added colours to it. Song was good, could have used it in a full length video.
