Finally finished! I feel my version looks a bit more intense than the original, maybe slightly more worried. The more I look at it, the more changes I see I could make to match the original more accurately. Whilst that seems to lead to a never-ending project, it is also one of the wonderful aspects of drawing or painting that I love; the more you look, the more you see, and you really come to know and appreciate that object in a different way than previously.
