I’ve been adding shading and hatching to the aerial view of Sandal Castle to create a more three-dimensional effect. I had intended to fade out the hedgerows around the perimeter but as the earthworks are looking so solid, I think that might be too much of a contrast.
I’ll probably add a few figures for scale and a few cars in the car park. I’m drawing with an Apple Pencil on my iPad Pro, using the program Adobe Fresco.
