Pigment powder and black ink done free hand. The picture is long so I had to scan it in sections and then use photoshop to stich it together. That is why you see a slight changing of the sky's color in the middle. In real life its not there.
All my art is scanned at a lower resolution to prevent theft. In real life the shading and detail are very pronounced.
Do you recognize the castle? How good is your knowledge of art and history?
