@polygondust Thanks for your feedback ! I have prepared a few High res renders for you: First the Orthographic view :Then a bigger Front and Back view
And some close ups :The problem was that i tried to cramp to many objects into two sheets, i actually took my time to Hand paint all of the textures.I admit that the Headphone details are really subtle. But if you have any tips on improving please tell me, hand painting textures is the newest subject i am learning. Or maybe the problem lies in the Lighting and Camera setup? (if the details are not big enough press right click on one of the Pictures and select view image)
