Trying this again, but differently/simpler than last time ( >>752290 ). I like that the original changeling design is such a fun mix between the familiar (looking similar to ponies) and the uncanny (insectoid and perforated legs), so I’m trying to replicate this in some way.  
Went with elves again cause they look similar to humans and are what changelings essentially were in original folklore/mythology, but since the insect aspect provides that certain unsettling feeling, I simply went with a completely insect lower half this time. I imagine that you’d see her peeking above some foliage, thinking to yourself “hey, she’s pretty cute”, but when you approach, she suddenly buzzes into the air and pins your arms with her legs.  
There’s so many directions you could take a humanoid changeling design and I feel I may never be completely satisfied, but for now…
