Artist's commentary
Asriel Dreemurr
Fanart of Asriel from Undertale! What a cool game.
(He actually looks nothing like this. I took a lot of artistic license with his design. :D (Big Grin)
)
EDIT: Since quite a few people have asked me now, yes you may cosplay this design! And feel free to send me pics of the finished thing, I'm very interested and flattered that you'd choose to make this.
