Undertaker Yorick's in-game model needs much more contrast in it's colour palette.
This looks horrible, especially in comparison to the that amazing splash art someone created for this skin. In the art, most of him is shrouded in darkness and the part of him you can see in the light of his lantern has some rich colour to it like the gold chain around his waist, the maroon like red accents against the seemingly black coat he is wearing. I don't know how that translated to such a boring colour palette but if you're going to rework Yorick finally, it should be done right and this is not it.
