Here's mine on Tomodachi life and Miitopia, I have two different appearances because I can't make up my mind. The one at the bottom is also used on my 3DS ID (I guess that's what it is..)
Mine just? looks like me, nothing too special. On Tomodachi is a whole other story.
I have all the best clothing, and the gold apartment, and all the songs, everything. I also have a propeller Mario, a Toad, Vinny's mii (he also has the best stuffs), miis of everyone else in the Vinesauce community, some memes like Bonzi Buddy, CATS from All Your Base, a Cloud Strife mii, every TF2 class (Yes, even Pyro who wears a gas mask 24/7, I applaud who made that mii because there isn't a gas mask item), Jon from Jontron, Egoraptor, Danny Sexbang, and so much more. I played that game to death. Hell, I even made a "metal" song about Mr Bones' Wild Ride. I might have an addiction, please help.
Tried making a person of colour/black Mii character on my 3DS Mii, think it turned out pretty well without being racist or anything. Looks pretty nice so might keep it for a bit.
My Miitomo Mii is pretty much me mixed with Sheila Charlesworth lel.
