I hope it's not too tacky to use this day as an excuse to make more art of my #1 ship, but when I looked it up and found out Fluttershy Day is when it is because of Arbor Day, I immediately thought of Big Mac gifting Fluttershy her very own apple tree outside her cottage. Considering Big Macintosh's family business, I don't think it's too much of a stretch to assume such a gift would be a very significant gift to him, and I'd say Fluttershy recognizes that.
I'm sorry to say this picture was late entirely due to laziness. I had the background done more than a week ago, decided to take a little break before finishing the rest of it, then had trouble finding the drive to get back to it.
