From my standpoint, My Little Pony is a good show, but it has little meaning in my art. Surely, my early pictures and some of the characters I include in to my drawings, are from the show. But while MLP was busy to reach season 9 (it's final season), I was busy to produce more and more personaliced characters and stories.
Ok, to be fair: I never really posted any stories or characters so far. Surely some, but not many.
One question could be, what are ponies for me? Do I define them by how the show presents them? No, ponies for me are what the community started to make of them. They made them silly, funny, playful and snuggly cuddling creatures, with all kind of weird character trades.
Ponies are not a single thing, that can be defined by terms like a "colourful-magic-horse". They have grown in to their own culture and many different ways.
(And they have conquered many different worlds.)
Ok, this is how I define the "Ponies". But why do I draw them?
I draw them because I just love their characteristics and appearance.
Do I only draw them? For the moment, mostly yes. But I work towards drawing other "things" as well.
