WOW!! Oh my gosh, I love this artwork SO much!! Masterpiece! I don't know where to begin... Okay so first I love the attention you've given to the terrain, Nature-ish places and forests are definitely my favorite kind of places, and the environment here is gorgeous : the design of the trees, of the clouds (amazingly beautiful clouds!!), the distant landscape, the objects on the ground, the tree's roots... Love the overall color scheme, too, you've captured the spirit of autumn perfectly! I wonder if the shape of that cloud was meant to resemble a moon on purpose, to complement the sun on this picture!

Then, I love the gentle scene, so nice and soothing. Then, I love just how fitting the actions are to the characters! Fluttershy being with animals... Rarity contemplating beauty... Applejack worrying for her sister... Sweetie Belle singing... Pinkie having fun... etc. You've captured the spirits of the characters so well, this might be one of the best tributes to those ponies that I have seen on DA. Special mention for the scene with Scootaloo being on top of Rainbow!! I just love the relationship between those two. And yes, I agree, Twilight being grumpy is SO adorable, especially on this picture!! I'm SO in love with her expression on this, and... simply with her! XD Spike's expression is great too. Seriously I think I might love Twilight on this just as much as the overall artwork... So many levels of appreciation in this!

Then... the lighting and shadowing is also pretty good.

Hmm I could talk about how much I love this for hours I think :/ So I better stop here.

In any case, amazing work!! :D My words aren't enough, but thank you so much for this! ^.^
