Digital Art of my OC "Nathan"

Nathan is an OC I created years ago and never got to flesh out his backstory.
He lives in a fictional place, inspired by the steampunk style and is a quiet, withdrawn person from the lower class.
It wouldn't be wise to bother him because there's quite some pent up anger hidden behind his facade.

Addition of colors, some grain texture and some shading beneath the character to place him onto the planes more tightly

Intermediate State: clean lines and simple greyscale cell shading
