D'aww, so cute dear! As has been said, Rarity truly is adorable here, and I meant what I said on TD's original picture about that hat always looking fantastic on her. Both of their expressions are perfect (I love Applejack's look of bemusement), and good for you for adding a full background! I really need to stop being so terribly lazy in that regard, honestly.
I do love it... I don't even know fully why. But, likely because I adore both Rarity and Applejack I suppose, and they're very entertaining when they're together. But anyhow! If you like FlutterDash, I really would encourage you to draw more of it, or whatever makes you happy really! That's what fanart is all about, or should be I imagine.
We all love our favorite ships. I'll agree that Rarity and Applejack are perfect together. Their clashing personalities and interests make for great comedic entertainment, while simultaneously opening the door for acceptance and compromise, which makes for a sweet and loving relationship. I can't stick with one preference the way you do, I ship ALL the ponies! Each pairing has certain qualities that make them stand out above the rest, some more than others.
Well, yes, I do believe you have hit on exactly why I adore that pairing so much, very well said! I enjoy the fact that it's great comedic material at times, but can also be very cute if handled correctly... depending on my mood and the fanwork in question there always seems to be some take on it which appeals to me. And yes, once I managed to accept the fact that I developed a fondness for a cartoon pony-ship I've become very loyal to it... with other characters though I tend to be far more accepting of various pairings, I suppose because I have little to no emotional investment in any of them especially.
