It was good, but had its problems.
You see, the animation was fine I think, but it's the muzzle that I'm thinking about. It was a little almost invisible puff of smoke that was about in front of the gun rather than on it. It wasn't really a muzzle flash, a muzzle flash is a flash of a gun when it shoots, not a puff of smoke. I recommend just doing it on a single frame like I do it on Gimp. It actually lets you draw a muzzle flash. Not bad though.
