Nice  You got a nice composition going and i wouldnt demean yourself on the effort / comparison here either. There is a lot of fun to be had with this concept. I handcuffed myself to a page with it (if interested). I've still got a self portrait i want to do with a similar use of a pencil now i am properly teaching myself how to sketch again rather than use filters.

In every stone sleeps a crystal.
Remember the Shaman, when he used to say:
Man is the dream of the Dolphin"
