Neat ! I really like both the style (even if I can't figure what the "staff" is supposed to be lol ) and animation (especially the disappearance, the fire is well done too), but something seems off to me : the part when the "staff" is going down. If it's an attack animation, I imagine the "staff" is supposed to pierce through the enemy then end it's course stuck in the ground ? If so, I can't help but think that it lacks speed or power to do so as it is. The "staff" goes down too "slowly" ... not sure how to describe it but it doesn't give the impression that you'll be pinned to the ground by some divine godly magical ass spear or whatever
Maybe make it go faster or add speed sfx ... ? Sorry I'm not am not of much help, I'm such a noob when it comes to giving art advices
