Compare the two skins. Though the colour scheme is similar, the only real similarity in pattern is the design on the clip. IMO it's a really good looking new skin, but everyone has their own opinion I guess.

P.S Same thing for the Vulcan; it has a similar colour scheme but is really different.

Edit: I didn't create this skin by the way, it's just annoying to see people hating on it for a few similarities it has with another skin.
