This is a sketch of Korean musical theatre actor Jeon Dong-seok in The Phantom of the Opera.
It is my first time attempting a finerliner/inked drawing like this. I can see I still need to work a lot on shading technique in this medium, but for a first attempt, I am fairly happy with how it turned out.
Drawn over approx. 3 hours with Staedtler Pigment Liners 0.05, 0.1, 0.3 and 0.8.
