She doesn't need to be able to shoot while jumping, but being able to shoot while walking and running would be very useful. Adding a second melee attack where she rears up and kicks with her forehooves would also be very useful.
To be clear though, the big issues are the scaling and angle difference between the moving poses and stationary poses.
The artist Otsoga has obviously put a lot of love and hard work into creating the centaur lady asset. And, despite the issues above, I like her a lot! Did I mention she's so cute!?
