First digital painting that isn't based on an existing image :yay. Though I used a photograph as partial reference for the face (shape and position of eyes, mouth, nose...) and the background is a modified stock image.
Done with Photoshop CS6 and Trust TB-4200. Worked on it for 4 days (approx. 16-20 hours).
