Hi.
I think it looks very nice, but as they (the long time members) always ask on here; what type and age tortoise will be living there? & What geographical region are you in? (I have spent hours on here, lol, & many initial replies ask for this info to better assess specific needs).
I am also trying to keep live plants, (some potted & some directly planted into substrate) to somewhat replicate a natural habitat for my RF hatchlings, luckily humidity isn't really an issue for coastal Florida!
Best of luck to you and your torti friend!
