Same terrible art style? If you are referring to actual stylings of how furry artists put lines and colours on canvas, then what you’ve done is seen a similar art style from two artists and then assumed the same for the rest.
If you’re talking about actual character proportions, oh boy! First of all, Sonic does not even come close to being a majority inspiration for furries; a way closer guess would be the Argonians and Khajiiti from Skyrim. Secondly, the whole point of furries is their fascination with this world of anthropomorphic animals; “anthropomorphic” means “human-like”, so of course the majority of furry characters would be animal races with human-like body proportions.
EDIT: bro’s really included a Google image search of “furry pfp” to try to prove his point without realizing that drawn profile pictures naturally have certain exaggerated features and clearly-defined lines to appear well when shrunk down to the size profile pictures are normally displayed. Easy counterpoint: now do a Google image search of “furry art”.
Because I’m not physically able to try the IEMs myself before I buy them? I’m not made of money, so I can’t keep buying and trying things until I find a perfect pair.
Look, I’ve bought stuff he has tuned, and I liked them enough to continue buying things he recommends. I also don’t mind tuning differences because at the end of the day as long as it still sounds great I’m not fussed.
