Build a live Forest moss wall terrarium with driftwood, dry moss, tutorial

The plants:
Neoregelia,
Ficus pumila 'Quercifolia'
begonia
1. The moss is dry Leucobryum moss. I sinked them in water for about 10 minutes.
2. This video records clearly how I make sticky mud with red clay soil. It looks familiar, right? If you make any experience making bread dough or noodle, it is the same way.
3. Neoregelia. See how you get new baby Neoregelia in this video? It does not need planting. In a terrarium, it is the air plant.
4. Ficus pumila 'Quercifolia' I hope it climbing over the glass panel, then cover most of the inner glass. In a terrarium, you put it inside and they begin to grow.
Welcome any questions.
