3D illusion with markers

In 1995 I bought my first Copic markers. Never used them but I kept o adding to the collection. SO I decided to give it a go.

I downloaded a reference picture from the internet, pulled it out of proportion and ended up with something I could use. It was done on a A3 sheet of cheep 240gsm card stock. I’m sure I can still go crazy and add 10 hours worth of detail but I only wanted to use the markers in this piece.
