It's a cute scene, and even if not perfectly polished I think the composition is really good: a somewhat rounded perspective to fit the whole meadow and a lot of the forest into the frame; a really nice trick with the very detailed leaf blocking the direct glare of the sunlight, and a very sweet form of Fluttershy aimlessly kicking the apple across the field. The impressions that she's just taking her time and a bit of sadness in her face make me think that she feels a bit small at the moment. Sometimes we have moments when we think the world wouldn't miss us, which is what she seems to be feeling here. (Or maybe I'm just readingtoo much into it.) You've created a great mood.If you're looking for critique then there are a couple of things in the layout thatcould be improved, but I'm not a real expert — I just play one on the Internet.
