A while back, MissWerehog offered a few slots for anyone wanting Sonic Channel art of their character(s) Knowing me, I just had to get one for my two Mobians, and never regretted for spending a dime for such wondrous work~ 💕
Also a small note to point out: I did some editing to make them out as wallpapers for personal use (I tried my very best to present them closely as possible to the official Sonic Channel wallpapers). The original versions (least for Yuki at the moment) can be found here. ...and apologies if this greatly offends the artist. >.<"
