Drawing done in class. I am designing some dark gothic castles inside a cavern. I selected 2 pieces of reference which provided me ideas for perspective, lighting, tone, and architectural details. Parts of the drawing are still unclear, but I focused on the placement, scale and overall impression of a castle.
A tonal sketch is the next step in the process of rendering this environment. I added a stone path in the foreground, some stone ruins, a stream, and a different castle shape.
