A Troll of caves

I present you my troll. It is not very beautiful, but after all ………. it is a troll.
Why a troll ? I was angry against a nasty and at the same time of stupid! My ancient boss! I wanted to draw something looking like him. To draw a troll seemed to me logical.
I am a fan of the trilogy of the Lord of Rings. So, I realized a troll of caves.
This drawing is made from a photo. I like very much my troll even if he has defects at the level drawing.

It’s a graphite drawing on A5 format and it’s my first drawing of a fantastic creature !
