I've been working on it about 4 days. On and of though. I wish it would have went faster.
Used reference from mjranum-stock
In addition I'm working on a series of studies and still lifes to get better and on an awesome secret project.
All of them are progressing slow.
Thought to add some progress too. Larger version here
Started with a black and white sketch and worked on one layer.
Sadly I merged the first sketches :/
