I painted hairs on the deer to look more like the deer in the hunting paintings, it also has the benefit of looking stylistically more different from the smooth painting style of the little deer. I also darkened up the shade side of the antlers to give them a little more definition.
When I work I usually leave my paper cartoon under my fabric and slide plastic underneath the fabric to create a barrier to the paper. Dry cleaning bags work great because they are thin soft plastic, easily smoothed out and less like likely to show creases.
The filigree scroll pattern was painted with an ocher brown transparent paint diluted with a lot of textile medium (colorless extender) that made a nice soft creamy yellow color.
It probably looks like I am getting close to being finished but I still have a lot of painting to do. I need to add gold to the scroll work to give it definition and I still have all the flowers and grasses to paint on the ground.
