Outstanding!
I'm with Brian on keeping it sparse - and how very clumsy they are... I suppose with a single specimen, there's less to worry about.
I think the whole twigs-on-the-top thing is perfect! Credit where it's due... was that Precarious that came up with it originally...?
To do it over again, I'd have even thinner branches on the top - I've got some artificial grape vines I'm working with now. I like how thin they are, but they give a little too much. I also use the coiled vines, but they don't seem to like molting from it. Interesting.
BTW, so far, my single Idolo specimen (watched VERY closely) has molted L2, L3, and L4 with exactly 18 days between each molt - like clockwork. Two days motionless before molting. About 40 hours before getting an appetite.
