The sounds seem perfectly baked into the mix, and do not stand out as being added. However, at times it sounds like the sound effect is looped back to its beginning partway through, rapidfire. I wonder if the first ‘instance’ of the sound that gets interrupted could fade out for half a second or something, letting it trail off rather than immediately being cut off. Like a toy that makes a sound, but if you hit it again it abruptly starts over.
Other than that at a few points (heard most at 1:26).

It’s quite possible, though, that I’m imagining this and the original effects you are using are already like that. I offer it just in case it’s at all helpful.
