My lines combine to spur an idea in the viewer’s head.

It is my perception that my lines come together
to represent a river, a wooden bridge, and stonework walls.
An archway. A landscape. Bricks.
In the background, one can see a town.

I wonder what the viewer sees.
Does anyone see just marks and scrapes?
Colored mud.

I wonder, what is the minimum amount of information I can provide while still conveying the same idea?

Note: Balance between suggestion and explicit representation.
