Good start. I'll throw out my thoughts.
- I think the timing needs work. The way she raises the gun looks a bit slow
- Maybe she should raise her arms higher?
- I'd recommend you check out the 12 principles of animations to discover the optimal ways to add "zazz" to this piece
- Check out actually reference video of women shooting handguns
Anyway, made some small edits that (IMO) improve the timing. One with swipe/one without. It's not perfect but I tried to give the animations some follow through with raising the arms up quickly.
