It's not a rip off because you were watching Kings of the Stone Age, but you should really embellish the textures more. I'd love to see that kind of auteurism adapted into a manga like they're done with Black Rock Shooter and RWBY. It's beautiful and your lines are incredible, but it has flaws, your sourcing is so exlusivve, it's not coming from anywhere else.
That is my critique of your ONE portfolio piece.
assuming I can get around back to this thing sometime this century
