The couch and background have been painted on and left to dry. Layers of his fur were then built up slowly blocking in the darks and lights. The collar has been blocked in and layers of brown will go over it to soften it more. He looks a little funny right now but will take shape soon enough.
The masking fluid is still on in areas but will come off soon. The lighting was not great for this photo so the coloring is a little off in areas, next update should be more accurate in color as it is 'supposed' to be sunny the rest of the week.
