I haven't seen a real pony in my life, so I cannot tell for sure. But they have prettty long bellies down there: th02.deviantart.net/fs71/PRE/i… So she IS touching her belly. Maybe they have some kind of special sensibility in there for some reason.
It was supposed to be a joke... I know what she is doing... And I mean that I've never seen a real MLP:FiM pony in my life... Maybe I haven't grow up with horses, but I guess ungulate anatomy is pretty similar to other mammals...
Clear. Just pony fandom is no such "agreement." For example, in Russian fanfiction "sudden desire to" location, uh, "place" as a woman, but the other authors adhere to the basic "animal" anatomy. Forgive my curiosity
I don't really practice one or another. I viewed such works of other artists and decided on the look that is appealing for me. I don't think that part is anatomically correct for humans or mares. I started to study human anatomy recently, though.
