This is my first terrarium btw
I'm happy with it for the most part. My only regrets are the pond in the back right (cant quite see it in the image), using so many types of plants instead of using a few plants in higher quantity for a more natural look, and those damn vines lol!
Oh! Also, the entire back ground was first coated with a mix of organic, fine black compost and wood glue and THEN a layer of cocofiber mixed with the wood glue. I used the compost so that over time through run off the compost might release nutrients to the plants. The larger vine on the right actually threw out a root that has traveled all across the wall
