I have a gif that I'm using for my spray but it doesn't loop perfectly, if anyone knows how to fix it, I'll give you some points. http://zippy.gfycat.com/TidyBruisedIndianelephant.webm
I'm not sure if you can fix this, if you look your person in the gif is moving slightly down which unless he moves up the it may always look like that :/ Edit: Actually it looks like it's just the circles around your guy not moving in a natural way.
