Rainbow Dash isn't speaking like Rainbow Dash, Fluttershy isn't speaking like Flutttershy. I simply can't imagine either of them saying "nor", I can't really describe what I'm feeling here, they just don't sound "right".
To put it better your dialogue does not fit the characters.
Har har, meme reference, Im summoning great rings of hellfire from the depths of the sea with my otherworldly, raucous, laughter turned up to eleven, the spasms from my diaphragm have become unbearably painful and my mouth is twisted into a void-like, toothy, gape. Let it be known that "What does the Fox say?" did indeed exist and your comment was both incredibly relevant, witty and totally not a non-sequitur. Truly this is a cop out to breed yet more sycophantic, brown-nosing yes men, ready to drop what they're doing to fill the comment section with more vapid, simplistic praise rather than genuine well-thought-out criticism.
This is why the deviant art community is filled with nothing but shitty OC drawings and ms paint because no one has the balls to critique anyone, especially those with talent.
Man, While incredibly verbose, and over-exaggerated, this comment was incredibly fun to write...
Disclaimer: This comic isn't terrible, the artwork looks hand drawn and looks decent by those standards, as I've said the dialogue is off and the story itself is hokey and a bit awkward to read. My comment was written for my own enjoyment and I do not genuinely hold such a level of contempt for yourmove17, nor am I completely certain he was making a reference to "What does the fox say?"
