High-res shots from this page.

Obviously I was really tired when doing some of these shots - I completely missed the problem with Rarity’s collar until I loaded it up this morning, and I don’t even remember doing the last shot on this page…

My concept for “Imoen” was that she’s literally a one-trick pony - magic missile is the only combat spell she knows, and she’s never had to use it in combat before, hence why she looks like she’d rather be anywhere else than here. (She’s really good at casting magic missile, obviously, since it’s her cutie mark… but that’s not really a comfort when you’re being called on to stymie Princess Celestia’s prize pupil).
