I did gani for like two days (it's so boring and easy), so take my advice with a pinch of salt.
The reload:
I like where it's going, but it could do with quite a lot of work.
Firstly,
to me it looks like the hand teleports from holding the gun to the clip. Allow it to move there.
Secondly, the position of the hand doesn't change throughout the entire reloading process. This removes the sense of realism as there's no way any person can reload a gun whilst maintaining their initial hand position when holding the weapon.
Could you emphasise the removal of the clip more?
The head movement is alright I guess.
The downwards reload looks neat
Fire:
For the size of the gun, I expected slightly more movement.
The player is very stiff.
Melee:
Never made any, so i don't think it's right to leave feedback on something you've never done.
From a players perspective, it looks ok.
