Wow this is insane. Do you happen to have the developer, I'd like to talk to him personally. This guy is talented enough to actually have some type of career waiting for him in game animation or development. I wonder if he has done anything else to this degree before. Do you have any other pieces of work solely by this individual?
This is really good quality art, not to mention the art-style displayed in it is one that many would die for. Whoever made this clearly isn't an amateur, or they're really talented, keep them coming!
Open up the link in a new tab and you're gonna get the name of the artist, search it on deviantArt and you can message him there.
