And this is just plain awesome. Friendship and forgiveness at its finest. Would not be surprised if Twilight was in a nearby bush with binoculars, taking notes while Spike naps.
It's such a tender moment, makes my heart warm .
My first thing would have been Sweetie's mane, why it looked so odd, but then I noticed the tub of water she's in (Honestly, I must be blind! Arrugh!). Other than that, it may have to be Bab's legs. Her hind legs seem very awkward, like she's about to just trip and plop over. The right fore hoof seems like it doesn't have bone structure, like it's "floppy" (not sure how to describe...).
The background could have used a few other items in it, maybe just as little as a few trees and a bush (as cover for Twilight). Despite that, it's absolutely beautiful scenery with that sunset, and the shadows take my breath away.
