First off, thank you very much Richard, Martin, Ernie, Warren, Alain, Stefan, Des, Richard, Michael, and Rick. Your generous comments are sincerely appreciated, and I apologize for my delayed response. The support from this community is incredible.
I am declaring this one done. The last major step for my to undertake was the Heine propeller, and as I think I made clear, I have been dragging my feet on this for some time. Having attempted various masking schemes I finally decided to attempt it free-hand with color pencils:


Better than I expected, given that I had no faith in my ability to mimic the lamination curves, but still rougher and less distinct than I would like. The base coat is Tamiya Desert Yellow (XF-59), and I colored the darker wood with various shades of brown pencils from Prismacolor and Derwent (primarily Dark Brown 946 from Prismacolor). In the interest of closure (the first post showing work in this thread was September 27th!) I decided that these results were close enough to what I want, but I am still trying to figure out a way to accurately map out the lamination curves for future builds...
I finished the propeller using Alclad Aqua Gloss, Alclad Aluminum for the hub, and Mr. Metal Color Stainless Steel for the nuts:

In addition to the prop, I added the lift handles to the rear of the fuselage, touched up a few spots here and there, and that was about it. I have not yet taken any decent pictures of the final results, but will post some when I do. I really enjoyed this build, and am happy with the final result. I have always liked the lines of the D.VII, and enjoy seeing this one now that it is all together. I am also very happy with the various after-market additions that I included: the Aviattic lozenge really looks beautiful, the Taurus BMW upgrades improve the kit engine significantly, the cowl nuts add a nice little bit of extra detail, and the Gaspatch LMGs are very convincing.
Thanks, once again, to everyone for following along with this glacial build, and especially to the many of you who were kind enough to leave comments. I am very grateful that so many of you took the time to participate in this with me.
