Body work empanage seam, HS/tail joint, and low spots on fuselage.
Photo 2 shows a dark grey section under the opera window after long block sanding. This is the low spot. Most of these low spots disappeared with additional sanding. A few required a bit of body filler. I'm not looking for perfect because perfect planes are heavy. I will flatten low spots on areas that will be seenfrequently such as the side of the fuselage and top of the empanage.
