For aesthetic purposes (not sure if you care about that at all lol) I would get rid of the whole hook and whatever is attached to the pot if you're not actually hanging it.
We have a small pothos at the bottom of our enclosure then a small ficus that Shooter (ambilobe) loves to sleep in on the right side and an umbrella tree on the left. We didn't want it completely cluttered. We also went to Michael's Craft Store and found a cheap vine that we draped from the back right corner to the front left corner that he loves to bask on. The branch-looking vines that are in there change a bit from time to time because we take everything out about once a week to clean out his enclosure but we try to put it all back as best as we can.
I would look into a different position for the thermometer as well, maybe outside of the enclosure. Not so sure I would tie it onto the branch he will be walking on/basking on. We used velcro and attached ours to the corner of the enclosure. Once again, we're big into things looking nice and neat, so that helps a lot. The thermometer we have slides onto the top of our light fixture.
Everyone has their own way of doing things ya know? I am in no way trying to tell you how you should do yours, but I figure a picture and description may help in giving you some extra ideas! I have no idea WHY the picture is sideways!!! Our enclosure is 18 x18 x 36 high.
