Mecha Arm

Hi y' all!
I was thinking about some procedural shading in Arnold for a while, and how it would be nice to try and make somethin out of it, and here it is! "Mecha Arm" is my first project, where I used node based techniques to create texture for my model. Not great, not terrible if you ask me, for a first time;))
C&C are welcome! All the best!;)
