In some frames, some lighter pixels appear near the edge (and one outside the outline on the front foot), those could use some clean-up. If the ones along the edge are meant to be the bread's other side showing through, then I think you need to exaggerate the motion so that it's much more obvious that it's the other side, have more frames showing the other side. Otherwise, it might be best to leave the backside unseen, as it just looks like a flash of noise.
Thank you for the feedback, that's a really good point!
