Great work slym I'm digging it.
My issue with this animation is how suitable it is to gameplay.
It would be pretty annoying to wait for that long between shots of such a small gun.
Perhaps consider modifying it so the gun also recoils upwards a little bit.
This is so you can segway into another loop where she's firing repeated shots.
Then you would go back to the end of this current animation where she needs to reload.
I also think the fade out line of the gunfire looks cool but is just a bit too slow.
And I think you could emphasize the gun flash more by lighting the front of her black shirt.
And see how it looks with a bit more on her face and a touch on her hair perhaps?
I'm dying to know about the environment
Have you got much ideas yet? Or still thinking about it?
