Got autistic so felt like analyzing the ones we've gotten so far
-mizutani has been very autistic about basing her Mikus on the pkmn they're paired up with, rather than the type they rep. This is most notable in fire(which is more like a skeledrige miku) and rock, which ended up looking like an ice miku due to the aurorus elements
-Kantaro(a TCG guy, I think he's fairly new) seems more focused on the type. His ice miku is pretty outlandish with the blocky like clothes and ice hair, reminded me of ice man exe from battle network. He seems to have focused on the element of ive itself. I like it tho.
-Kannu's Miku's are more based on the type liks Kantaro, rather than the individual mon like Mizutani. Rather than focusing on the element of the type like kantaro, he seems to give Miku jobs related, either closely or losely, to the type. Elec Miku seems to be an electrician, and Ground Miku is some sort of explorer/wanderer, which is a way more loose connection desu. Also, his concept sheets tend to include extra mons and some easter eggs like the mirage tower.
-take has only done psy Miku so far, and it doesn't seem like he focused too much on the type OR the Pokemon, and just focused on the main premise of "what pkmn would Miku use if she was a psy type user", and he just designed an outfit he thought looked nice. The ribbon on her hair looks like the "ears" on meloetta's earphone/speaker thing, and that's about it. And her bag has some easter eggs like stickers of odl school gen 1 sprites.
