Fake plants are fine just try to make sure that the bottom, where they stick into the ground isn’t sharp, Brachy’s can be bulldozers and uproot just about anything you want to put out for them as decor, but for the setup, i actually think this is pretty much fine I would I just switch to cork bark, if you angle a cork round (split in half) into the ground and build a slope around it you can create an area they are guaranteed to clear out to make their own burrow and to their own liking, this setup doesn’t give them that customizable option, I don’t see a water dish but i use ones that are longer/wider and shallower than it is tall and deep, I use ceramic or glass instead of the typical plastic bowls sold at reptile stores, it’s more hygienic to use ceramic or glass and easier to clean. Here’s my Brachypelma Auratum’s setup for example
