Hmm, is this considered fanart? Can one 'fanart' one's own deer?
Anyway, Grim wore the deer mask for a while with the default antlers, though in my head I was picturing them more like this. If there's one thing I miss about the deer mask, its the sound of Grim's bellow when he was wearing it. Too bad the orca mask doesn't have any effect on that (an interestingly sing-song sort of whale-influenced call would be awesome!).
Apologies for the lazy colour-job; fatigue isn't conducive to good arting. *cough*
