Previously, for the Excaliburn and Dandelion Zetterburn skins, Zetter's right hand - the one holding the sword/bouquet - was modified in their victory animations for better posing with the item. This seems to have been lost in the 1.5.3 patch, where their hands have gone back to default posing and, as a result, an awkward visual on the final money shot.
See attached screenshot - left is the animation in previous patches, right is the animation in 1.5.3.
