Years ago I had a piece of balsa, some spray cans and a strange style in Graffiti, I decided to make some masks with one of my simple sketch, and this was the result. I painted with some tempera, then spray painted the piece of balsa to make a backgorund, I drew something, then spray paint again to made it seems like it was fading, then spray painted with the masks i made, and shaded again with spray paint, than again I ritraced only some of the elements with some paint markers.
I liked the final effect, with a little bit of tempera visible, the violet part, and the background with only blue and white spray paint, the same paint in the central graffito, and only a black and a silver paint markers, I have taken apart the masks I made, thinking of make some other color variant, but I never made it.
