HorseyyGal: Sorry, that's a really cute picture but it's a bit too small, I don't think I'd be able to do a very good job on details for the faces. If you have any bigger pictures, feel free to post them though. :)
Lilruffian: Thank you! I don't have much experience with people yet so I'm glad you like them. :) Those are some really nice reference pictures, they'd definitely make good paintings.
Pony10Girl: Thanks, I had to borrow a magazine for a reference so I ended up doing a painting of Reba McEntire. XD
I like the first of your pictures, but I'd prefer to do more of a full-body poses rather than face, but I might try drawing it with graphite sometime if that's alright.
