its easier to just move the entire sheet about 10 pixels to the right. then to edit the right facing attacks to not overlap in the next frame than it is setting pivots in editors, had to delete and smoth off some of the slassh right animation, and still moving around thos same animations at the moment to get the centre.
as hobbyists its vital sprites are centred on a canvas with equal pixel size. as the time it takes to get them ready is on par with using homemade assets.
also the slash attack for the right facing frames is missing 2 frames, compared to the other facings
