Medusa Blue, Silver, and Gold Picture

This is a design I've been thinking about for a long time. Originally, I wanted to make her skin darker, more like the dark blue I used for the branches, but then what would I do about the branches? I'm very happy that the gold and silver ink scanned properly, though I wish my markers acted more like pencils - they darken when they overlap.
