Watercolor on Canson Montval CP 140lb, treated with acrylic gloss gel medium in some areas. 9x12". Photo reference: Angela from Julia Kay's Portrait Party.
For those interested to know what "treated with acrylic gloss gel medium" means, here is what happened. After I decided on the composition, I wanted some extra texture in her hair. I accomplished that by taking some gel medium and brushing it on the blank sheet of paper with a 1" bristle brush. You can see the lines in the upper and lower left and grain throughout the painting. The lines are the result of a little more medium on the brush; the grain effect happens when you drag an almost dry brush across the paper and the medium catches only the very top of the paper grain.
I uploaded a larger than usual image for you to see the texture close-up. Needless to say, I would be very upset if somebody used this image for their own commercial purposes. So don't :).
