Another illustration for a book and also practice.
A bit of photographic material here. (i.e. the shoe and pillars) There are custom brushes you could use that would give you a similar but more painterly effect. The snake looks good and close up photographic detail is fine. The reds and oranges in the sky are contrasting a lil to strong for me. Overall, I like the shot. I had that a similar one in my head.
