Kandicore isn't actually a full aesthetic; rather a combination of other aesthetics. Decora, scene, kidcore and others have many Kandi elements, and kandicore is purely focused on Kandi. If you are interested in Kandi I suggest you look at the aesthetics previously mentioned, and just work around the other elements.
Fawncore is an aesthetic based around fawns. They are animals and have their own distinctive visual. Kandi is an accessory used by many many aesthetics, and therefor does not have a specific visual. An aesthetic can be a subgenre of another aesthetic, but it has to also have its own visual. Kandicore does not have this, therefor it does not qualify as an aesthetic. Understand?
