I've been working on this project for a co-worker for a while. I'm basically done, but before I finalize for printing, I'm trying to decide if I should put some details inside the hollow tree (e.g. fungus, ferns, etc.). I am thinking I will purchase some wargaming miniature grass, leaves, and moss to fill in the blank portions. Has anyone worked with wargaming minis before? Also, I am planning to glue some translucent material (rice paper?) to the wing structure (probably just on one side of each wing, not both). Any ideas or suggestions on materials or process? Any other thoughts?
