I love it (AF dependent my whole life, so I might be biased)! Especially the cutouts on the jets!
I’m a “stacker” myself (Security Police Badge), so I’d be tempted to start gluing stuff on top of it…I could see the patch in walnut and maple, maybe the 2 jets in basswood and either mounted or inset…but you asked for “finishing,” not “starting all over again.” (THIS is why I have such a hard time finishing things!!!)
Maybe just a touch of color? Nothing garish, just a hint of squadron colors in the patch, maybe a pale gray wash on the jets?
Or leave it just like it is, because it’s already very nice!
