It's that girl, with the flame lance, FE9...!!!!
P...Pet...Petunia? Petinia? no... Petrine? Petrinia? Petrune? Petrunia? :\ I hate this game.
Hair is odd, I don't like the style of the strands, it's too bad you aren't doing some other style where the sprites are bigger, you aren't going to get an amazing portrait of Petunia without having the room to build on her, however you can still get a great one (what you have ATM). There are some parts of her that bother me but are technically accurate so I can't complain. I don't like how the top of her forhead is cut-off by a straight line though, it looks punctual and bad IMUO, the shoulder pad looks like it's raised too much, the outline looks a little choppy and I'd recommend going over it and looking for any minor fixes, if I'm being too vague as usual I could touch it up myself and see if what I am trying to point out means anything and then show you the slightly touched up version and whether it makes it better or worse and whether you want to apply it to your own work or not; sometimes there are things that are pointed out by me that don't actually need to be fixed...
Wow wall of text ranting, bad habit, just ignore this post kay XDD
Good job with the eyes, considering the difficulty of them, you have really improved since your first draft of Ace's sprite,

, good times, I still wish I had half your spriting talent.
Now go sprite an FE style batmobile
