I am new to animating guns and wanted to test my skills.
I have never done an animations like this before (with just linear keyframes) and I thought I did decently well for a first try of something like this.
This animation took me a while to make and this is probably the most complex animation I’ve made so far.

Opinions or constructive criticism would be greatly appreciated.
In my opinion, the floating arm looks weird.
The arm looks a little off when its detatched but its pretty good and woild most likely look more natural in first person
can you show what it looks like in first person?
I might some time later. I do realize that it is a little hard to see in detail in third person.
You should fix the problem of the flying arms, except if your game is about Zombie-Soldiers 
Alright I mostly fixed the arm floating so far away from the body now. It still does a bit because it kinda has to but I made it much less noticeable. (For me at least)
As an animator, I think it is overdone, the hands are moving so weird, It keeps moving from place to place, making the movement feel so unnatural overall, and also try to mag keeping in the hands smoothly.
I recommended making it more simple and instead focusing on timing and easing.
Seems fine. but could use then again. the floating arm to be a bit close to the body, and also some flow
