Feline = oversaturated. Also overused as an alt costume motif. Motif no longer tells much about the content type that the streamer produce). Has great diversity. (nyanners, okayu, fumino tamaki, botan)
Ruminant = Kalm. Niche audience. (Wataamr, Fauna)
Bird / Flying motif = only uses the color scheme and lore. Mainly associated eith streamers that does a lot of chatting content. (Subaru, Kiara, Lui, Elira.)
Fish / Marine = not only uses the color scheme, also has shapes in the design that respects it. They are carnivorous, yet have a bubbly look to them. Gap moe. Blue/Green is the main color scheme, and also the most popular color voted in surveys for its calming effect. Who are vtuber audience? Tired drones salaryman who likes to read Getsuyoubi no tawawa (monday blues). Can make "wet" joke while staying in character without getting backlashes. (Gura, Finana, Sumi, Bao, Chloe, Artemis) From the list, it seems like having a voice that will appeal to otaku-kun or UOOOHHH gang is a must...
Canine = The cat card without being a cat. They will be forever seen as a subset of the cat genre. Generally streamers with playful personality should be shoved in here. (Fubuki, Mio, Koyori, Korone)
Chuuni fantasy (witch/dragon/knight/demon lord/elf/god) = can work well if the streamer personality matches the model. Otherwise it is a debuff. (Laplus, Noel, Flare, Calliope, Zen, Debiru, Roa, Shion, Omega, Kronii)
Angel = UwU. Nothing offending. But there is less chance of being clipped thus less chance of growth. (Uto, Kanata)
Rodent (rabbit/rat) = the personality must be explosive otherwise it is a letdown no matter how good the design and rig is. Hard execution. (Pekora, Baelz, Tomari Mari, Haneru)
Normal outfit human = I don't think an EN audience for this will explode because the pandering possibility is too low. + Techwear/streetwear is an additional bonus if you are a highly skilled FPS gamer. (Uruka, 90% of Nijisanji, indies)
