I just recently started to write stories directly towards the FiM actively, though I have been writing for years, publishing numerous stories at Mibba and the eventual pony story, as far as to the MLP
Anthropomorphic requires that the character is walking upright in a Human like fashion and i inteligent enough to act like one. By the same standards, it also requires that there is enough of (in this case) the Pony.
There is little to no other requirements on the characterin question.
I love the good stories, the once you love reading and thus compliment and vote for.
Yet, it seems i tend to love continuing the stories where I didn't have so many votes or compliments, just as much or even more. Is this just for the love of the story, or is it something else? I sure did enjoy the story as I created and published it, that isn't the problem.
