I like it!
I'm working on taking branches from a model RR tree & doing something similar to my M26. The sale is off, but you'll never know they'll just look like brush instead if tree limbs.
I have a selection of material from aquarium plants that looks ok, but needs painting to enhance the effect.
Best option I've seen is to use twisted wire covered in paper & white glue for branches with loam or scale leaves added.
I even 'liberated' a couple of sections off a plastic plant in an IKEA display to try.
Well, Doc, to be honest it looks a little like something from the Great Barrier Reef, rather than foliage- and definitely needs shades of green; unless it represents a Sherman from the Pacific campaign... As you say, it's just a try out. Love the rest of the build.
