I think this version of Spike might work, as it does preserve that cross-species aspect of his would-be relationship with Rarity. That, and it serves to remind us that this humanized version of MLP is still very much a fantasy setting (as if the wings and elfin ears weren't enough).
Out of curiosity, do you anthro anything that's not a pony and/or animal-level? Cause if that's true, I kinda like it (even though I also like humanizing pony-level characters) and would like to use it in some of my stories if you don't mind.
Honestly, I prefer him like this. Seeing dragon-Spike and the human six is better, because, well, there's nothing really to differ him from the others.
In the show, they address how he's a different species, so this version of him makes more sense then the other more human one. (Who came off kind of orky...not that I have a problem with that. I'm an Ork lover.)
Good job by the way.
And may the WAAAAAAAAAAAAAAAGGGGGGGGGGGGGHHHHHHHH! be with you.
Kinda cool?...Youz dun know enuv 'bout da orkz. Theyz da best an' beatz the snot outa dem 'umie gits an' dem space elves. Even da metal 'eads and bugz, an' dem chaos snotlings 're afraid of us. Learnz dat an' weez might get along.
I like your version of humanized MLP:FIM. I was searching for a decent humanized version across DA, but you're the only one who shares my idea of Unicorns=Elves, Pegasi=Angels, Earth Ponies=Humans, and Dragonsragons.
