I've been wanting to make an attempt at drawing Applebloom with a hairstyle that mimics the general shape of her hair in the show but rendered "realistically" (kind of like what I did with Pinkie Pie). Granted, she's probably way too energetic to keep perfect ringlets like that for long, but this is a universe where horses talk, so yah =P

I'll probably do the same thing with Sweetie Belle, since I also wonder what a "realistic" version of her hair would look like. Scootaloo's hair is a lot more straightforward, tho.
