Personally, the more show accurate the art is the better it is for me and the harder my boner gets because it’s closely resembles the character. XD

It also has to do with how the “show accurate” theme includess regularly-sized breasts. Dunno about you, but sometimes I get a bit tired of the endless piles of imagery depicting Fluttershy with huge, sometimes impossibly-oversized bazongas. That kind of art can be done nicely to a point, but oftentimes people go overboard and it goes from pleasant to distracting far too quickly. Not only that, but modest features is simply a nice change of pace now and then.
