It's based on a wonderful mini from Smart Max. As soon as I saw the sculpt, I thought it'd make a great real-life costume. Not only is the figure dynamic, but its design taps into the archetypal hallmarks of a phantom - chains, billowing white dress, candelabra etc.
I'm not very happy with the borders of my illustration. Watercolour pencils, although portable and handy, are not good when you need to cover areas of more than an inch or so square. In addition, and as I've mentioned before, the pages of Moleskines don't hold liquids that well. Nonetheless, I do enjoy having a Moleskine as a repository for my work. They do make versions with watercolour block pages, so I may investigate.
