First off, it's just fun to see the two out on a "date," especially with Big Macintosh's bow tie and combed mane. Also it must be unusual (maybe uncomfortable) for such a big stallion to be around somepony even taller than he. Fortunately she's sweet and playful – and adorably awkward – that I'm sure they'll end up having a good time once they relax a bit. Excellent job on the two, plus really nice work on the background.
