The boobs may be inverted in their movements, but it still VERY much so works in the images favor. Like, it doesn't look like it was done wrong at all tbh. Just looks like they're going down with her and coming up with her in a static fashion, which is common to old school animated pixel art to begin with, and just a part of the general aesthetic that we all love imo.
Have you ever considered animating a fighting bowsette for Saltybets btw? I feel like your pixel art would be fantaaaaaastic in their circuits. <3<3<3
