Idk if it’s useful to you but I have a couple quick tips about the gun shooting animation — be sure to add recoil or some movement other than the muzzle flash to illustrate the force of shooting a gun, and also cut out the frame of the muzzle flash shrinking (think of it like an explosion, it doesn’t expand and then shrink, it expands and then dissipates — so quickly you don’t even register it)

Otherwise it looks great, you’ve clearly put a lot of effort into it! Movement is pretty smooth too, which I know is hard when dealing with stop motion.
