Need some constructive criticism on these animations

So I’ve animated quite some bit the last 2 months or so, and I would really like some constructive criticism. This is what I got so far:

Weapons:

First gesture (only worked on it for half an hour or so):

So yeah, if you got some hints and tips I would really appreciate them, cause I really like doing animations.

Find your weapon animations amazing. Though when you reloaded the pistol and put it back up, it looked as if a robot was aiming.

It all looks good to me

Ok, cool I guess.
