Honestly, it was a great treat to see my artwork on some official merchandise, as was being able to give copies to family and friends (everyone who had their artwork selected was given a box of the trading cards and a bunch of copies of their own card.) I'm not sure if the cards are still readily available in stores (they've released trading cards based on the MLP movie since then), but I'm sure there are copies out there on Ebay and the like if someone wants to go hunting for one for their collection.
Honestly, I hope that Enterplay does another contest like this again, because it was a real treat to see the many fan artworks included, let alone be a part of creating one.
And we all know where that led.
Also, just going off of my own brother's personality (younger, but still huge, a farmer by birth, silent, shy, and yet wise beyond his years), I think Big Mac would be inordinately upset over any damage to his first yoke. That notch in it? Probably sent him into tears at the thought of disappointing his family. Even after AJ and Granny Smith would console him over it, he'd never quite get over the memory that his first yoke, that symbol of responsibility, was damaged on his watch.
It's wonderful to see that special day when their hard-working little puppy came home. She's a true cutie, and little Applejack's excitement shines as she drops low to be right down there with Winona, flashing the best kind of joyful smile. (This is one instance where it's quite alright for Applejack to be a silly pony.) I think Big Macintosh adores his little sister as much as he does Winona, though if he forgets to give the dog that bone he may develop a taste for it himself.
