I really loved this, a tad too dark in some areas which makes the chrome metals just look pitch black with some really sharp highlights on them.
In these cases, you'd probably want to reduce the metalness of the material a little bit and spread out the roughness just a notch, just so it reads a little bit more of the color map and it wont soak so much blackness from the environment.
Other than that, some really cool shit here man, put it on the marketplace!!
