So I finally got around to doing that redline. It's not my best work but I hope it gives you a little idea of what I'm talking about.
I tried to illustrate what I meant by the arm. The way you fixed the arm made the upper arm look way too long and the forearm looks broken. In addition, you need to define the curves of her hips and abdomen more. Don't pay much attention to my legs and their lengths as I think they're off a bit. At any rate, I hope this helps in some way.
