"Real me...real me!" Definitely not a background Pony, you neighsayers! All 6.1 (Princess TS) were wonderfully done. Their eyes, manes, feathers & shading are among the best I've seen this year. I hope you find time for any other background Ponies you like.
A lack of Spike while his six closest friends are included usually irks me, but only when the subject is, “Twilight and her friends.” Because in those cases, the author/artist/what-have-you is forgetting that the show is about friendship, not ponies, and that he is Twilight’s closest friend. “Mane six” pictures are great, but I feel it's important to remind people he's part of that group of friends too.
So I'm not taking issue with the characters you chose to draw, although admittedly I haven't been in an optimistic frame of mind in that regard. In EqD's last six Drawfriends, the number of appearances for the mane six, both princesses, each CMC and Derpy have totaled in the double digits while Spike has appeared a whopping three times. Recently, I've been finding it hard to take any pleasure in mane six artwork, no matter how fantastic it is.
