Oh and the water bowl. I'd swap it for a plastic food container (my missus gets fed up with me diverting ready meal tubs from the recycling bin and piling them up in case I need another water bowl, they also make good hides if you cut holes in them).
You want something that is difficult to tip over because wet substrate isn't a good thing. That also means the water bowl should be on the bottom of the viv with the substrate piled around the sides. I can't tell from your photo but it looks like the water bowl is on top of the substrate and has sloping sides that could give leverage to push it over.
