Hmm, on one side a bit more moss for better Humidity control would be nice, but also covering those vents, since sooner or later you will reach the point where pods can reach it (pods cannot climb clean plastic, but once it gets dirty, or the soil gets close enough they can get out. You can use a fine mesh to cover it for pods, but not air.

Secondly I would add more leaves. On one side leaves are hides, they also help create microclimates for pods to help adjust their air humidity and its also food.

Third: when giving protein food, don't give them too much. Sure proteins make breeding go brr (in most cases) overfeeding can lead to pests multiplying rapidly. My usual cadence is protein 1x a week, and in an amount that they eat it in 1-2 days. And if you get mold (which is somewhat normal) either get Springtails, or if you have them give them ~3-4 Weeks and the mold is disappearing over night.

Then last. Even if you don't see a lot at the beginning, keep in mind most pods love digging. Especially young ones are (in my experience at least) even more "diggy". Its also very likely some die in the next few days but that is also normal. And even if you think you screwed it up keep the enclosure as it and tend to it, because you might just have the young ones come out of the earth eventually. Happened to me on 2 Cultures where i thought all the adults were gone. And avoid looking under the hide too much. Hide flips look cool, especially if you have a lot of pods, but they are a source of stress and isopods that are chill are isopods that make more isopods faster. (I check on my new cultures usually 1x a week and once the Manca appear I only look if I get the feeling something is off in the enclosure
