Dumpster Behind a Cyborg Repair Shop

Elaborate abstract doodle composed mostly of industrial parts.
This is the first doodle I drew with the goal in mind of creating a piece of art, rather than just passing time. I used Kuretake Bimoji carbon ink brush pens on 300gsm Winsor & Newton watercolor paper. The original size is slightly larger than A4. If you like it, I invite you to check out the relevant shop section.
