This morning I did a few more hours but it is slow going as I work out where the washes of colour start and end. It is faster once I start glazing layers of washes to build up depth of colour. So far today I added a blue wash in some of the glass. This will end up as a highlight and be mostly covered by darker colours later. I also added another dark wash on the background and some of the shadows. It is difficult to get a good photo with so much contrast between the dark background and the white paper. The photos will look better as I get more paper covered.
Speaking of paper, this lightweight paper is still driving me crazy with the buckling. I won't use it again unless it is glued to a support (which is what I usually do).
