Braille like drawing impressions

My latest drawings are Braille like impressions of the surface.

Nice placement with this graffiti, for a project playing with concept of Braille and co-hearing ... a play on sticking together in a mass and the action requiring two people to hear, to listen, to come together, to cohere.

Colour of paper as sun is moving to its wintery west sunset position. Shame I can't capture the wall texture in shot contrast too high.
