They share an unbreakable brotherly bond. Tails is always there to support Sonic on his adventures and Sonic always leads by example and gives his little bro the best advice he can. No doubt, these two are great friends. About this piece of art, however...oh my god. This is some impressive work here. What do you use to make these and where do you get the models and backgrounds. I don't think I've seen such impressive and such high quality 3D models except in ACTUAL Sonic games.
