I like the natural color appearance. Not black. Not white. Not grey. I think the coloration creates to much of a contrast and can look forced. I’d use a preservative over the natural deadwood. Applied probably twice a year. Immediately after application the preservative will darken the wood, but after some sun an a few weeks it returns to a more natural look....just a little darkened. Over time the natural color displays quite nicely. I think the tree character would come through better this way....look older and weathered...more pleasing to the eye and camera.....much less artificial. I really like that initial deadwood area. Fabulous rugged character. My thoughts.
