Rate my enclosures pls!

First time mantis parent here… I got two Chinese mantis nymphs (named .jpeg and .pdf) two weeks ago. They’ve both had their first molt in their enclosures with no problems. How do my setups look? I think the one might be a bit too crowded. I tried to leave large open areas for molting but I wouldn’t doubt if these dummies molted a cm above the ground. Anyways, I plan to turn them bioactive soon to combat dead feeders and mold. Thoughts? Advice?

(Btw I’m quite proud of my innovative idea to use cross-stitch fabric as a lid! It’s sturdy while being very breathable and grippy!! 🤓I’m sure I’m doing something wrong with the enclosures tho so I won’t be too cocky)
