Plant Suggestions?

This is my new 90 x 45 x 90 I have been working on for nearly six months now. My vision for this scape is to have the background covered in climbing plants, the hardscape to be covered with species of ferns, miniature orchids and bromeliads, and the bottom half to be very moody with plants that are darker in colour.

Current plant list:

Lower half:
Philodendron Melanochrysum
Syngonium Aurea Podophyllum Variegata
Amydrium medium 'Silver'
Episcia Cupreata ‘Silver’
Episcia Cupreata ‘Copper’
Peperomia Albovittata
Peperomia Caperata

Climbing plants:
Scindapsus ‘Silver lady’
Monstera Dubia
Pellionia Repens
Monstera Siltepecana

Plants on the hardscape:
Actiniopteris australis
Doryopteris Cordata
Vriesea Splerinet
Neoregelia ‘Tar Baby’
Neoregelia ‘Eteria’
Neoregelia ‘Punctatissima’
Neoregelia ‘Mephisto’
Neoregelia Rubrifolia
Pleurothallis Grobyi ‘Costa Rica mini’
Pleurothallis Minutalis
Tillandsia Caput Medusae
Tillandsia Bulbosa
Tillandsia Pruinosa ‘Guatemala’
Tillandsia Andreana
Tillandsia Ioantha Vanhyningii

As I am housing a gargoyle gecko in this vivarium, all broms will have their spines trimmed off to prevent harm to the gecko. I also understand that some of these plants do pose a toxicity effect as a result of eating them. I have owned my boy for 7 months now and he has never tried to eat his plants once so I am confident that will be the case in this new terrarium. If not, then the plants posing the risk will be removed.

My question is regarding any other plant suggestions or criticisms if any of these plants are not a good idea. I’m also interested in finding out more species of plants that could grow freely attached to the background that are not climbing plants.
