An illustration I made for my portfolio specifically for a book company, so this is my cover example (it is not official). The novel I chose is The Twelve kingdoms; Shadow of the Moon, The Sea of Shadow (first book), and it is probably my all time favorite book series. Originally Japanese, so it might be a bit hard to get your hands on it. But if you can, I really recommend it!
I must say, I feel really proud of this one. It was pretty quick and pain-free to work on. :)
