I sketched the concept roughly on a usual white paper. Then I drew the skeleton on a tracing paper using mechanical pencil. After that on another tracing paper, I drew the body and just fill it with pencil. I used tracing paper again to re-draw the body carefully without filling it. Last step on a new tracing paper, I followed my drawing with pen and filled it for the final look.
I scanned the last tracing paper and edited on Adobe Photoshop and Illustrator for vectoring and making some texture effects.
