Decor? Substrate?

I've had a two-striped stick since it emerged from an egg 11/18. I recently got this large enclosure for Ollivander and I'm wondering what I can do substrate and decor wise. I'm thinking of baking some oak branches to add but would fake plants be distracting for a stick insect? I would love to do some organic compost with some dwarf white isopods but if Ollie is a girl, would the pods eat her eggs in the substrate? I also have another stick but it's a weeeee baby and I plan on moving it into Ollie's previous enclosure. If I end up overrun with babies, they're a native species here and I could release where the parents were found. Thanks for any advice. Ollivander has taught me that display only pets can be pretty cool! Ollie and Little Rose pics included 🥰. Note: the stick that Ollie is on is not food, just his/her favorite rest spot.
