Yes, I'd say that is actually closer, but when the arm cannon is facing directly up it looks like her head is looking up again. I'd edit that so that it had the same head as the initial frame. You might also consider some 'motion blur' (a short trail of solid pixels, slightly shaded from where the cannon 'was' to where it is') to make it feel like the cannon was just jerked back.
