Yup, because the pep model doesn't exist or can't be built...
The pic below that I took earlier today must be a shop too I guess
The detail on the blade looks odd because it's the game texture expanded to fit on a life-size print of the model. And tbh the shadows and lighting looks consistent to me, the blade itself looks weird because the shading/texture is printed on, it looks weird irl.
As the freelance graphic artist who did my EVA helm said when I showed him earlier "the blurrry texture screams dodgy to me, but if it were printed like that, that'd explain it. Not shopped, but looks ropey as ****, the lightsourcing baked into it does'nt help."
It'll be interesting to see other pics from the owner tbh as his builds cleaner than mine and complete, mines just the blade.
