I love the idea of the orchid mantis and the pit!
Love the isometric map, but I did have trouble keeping track of entrances and exits on the actual map. More callouts would fix this I think.
Also some of the callouts are ambiguous as to what they are pointing at. The line under Orchid Mantis for example. Maybe put a light box around the call outs and make sure the line connects with the box.
Tree sketch was also not clear at first that there was a hole in the middle. Maybe add a dashed line down the middle? I like the sketch just think it’s a lost opportunity to explain the concept in a short module.
Really dig the beetle sketch and the cover. More beetle like sketches for all the creatures would be awesome. I just really like the sketch.
Basically a few tweaks will make it much quicker to absorb!
