My first terranium

I just found this bowl in my local super cheap shop and thought I would have a go at creating a terrarium!!

I started by putting some soil in the bottom then a few interesting pebbles I connected from the beach over summer. I then added a nerve plant baby and a few little succulents. i tried to keep the plants small so they won't go crazy too quickly and I can watch them grow. Then I sprinkled a few crystals over the top. I want to add a few crytsals and maybe a little lovers figurine on the rocks but I don't have one small enough right now so will go on the look out. Does anyone else have a terranium?
