Okay, I just generally love your art, so this is probably just gonna be one of those fan rants, but lemme get something straight: Clothing. Spike in boxers is fine, but I really thought that the clothes would reflect the person (pony?) A little more, like giving Babs something a little more city girl, or Scootaloo in something more... exercise-y? If u know what I mean... but over all, this is a good pic, nice art, I love Spike tagging along, and Sweetie made me smile, so keep up the good work, and don't listen to idiots like me :3 Merry Christmas!
spike's blush is adorable, sweetiebell's nighty is so cute, applebloom's shorts and tanktop are perfect for her personality, and i like how scootaloo and babsseed have similar outfits (since their personalities are a bit similar)
most of the time when i see pics of the CMC's in their underwear it's an overly sexual picture. but this has a kind of innocence about it. i really like it. so far it's one of my favorite pics like this.
all the outfits fit the character's personality and compliment how you have drawn them. a wonderfully perfect picture.
