with regards to the recoil, the law of reaction would only apply as you state for the initial recoil, the bracing against the recoil would provide the return to starting position.  If this was over-braced (more push by person than by gun recoil) then the gun would overshoot its original position.  The speed it returned would also be governed by the dynamic between the gun recoil energy falloff and the lessening appropriate opposing force applied by the wielder. if the wielder did not push against the recoil the gun would not return to its starting position, if the wielder on the other hand continued to apply a constant amount opposing force after the force of the shot diminished the distance of gun return would be limited only by the length of his arms. or im completely wrong and just raving offtopicly.

on topic: i think you should delay the recoil movement slightly, the body seems to recoil fully before the flash.

i love this painting style of pixelart.  i approve, and bonus marks for finishing.

You don't need to rip!  This is a great start... and for some reason I am really liking the highlight style on the hair.
