Nice! I like it. Hope your little one is doing better. Do you have a spray bottle? I would spray the substrate or pour some water and mix it by hand to get the humidity up. They like to be a bit more humid (70%).
You could also buy a light stand to mount the MVB bulb vertically (they are about $30). I really like the addition of the plants. It'll make him feel safe. I think he will outgrow the table in about a year and it's actually quite fun to build him a new one. All the best!
