While the two are obviously similar, the colors are quite different when you put them side by side -- for example, the bones aren't white in the new piece of skin art.
I understand that this is a slightly different color after you dragged the RGB-color 10 pixels to the left. But I hope you understand people find this a lazy effort to create a new skin. The skeleton skin has two colors so you could have make a white skin and red bones (no idea if that exists already) or some other combination, even an ugly combination like purple skin and orange bones would be more logical.
I get that you created a "New" skin but already make the changes so big, like light and dark red, that people can see it.
With the cybers most of the skin isn't visible and then nobody is going to see that you have an exclusive skin or the skin everyone has from last event.
I like that you created a new skin pattern this event, but I already can see next years event with the same skins but slightly different RBG colors and sell it again an
