I, personally, don't see her tilted too much in either direction. Even when I mirrored it.
I also made an edit, just to try to polish her a little more since she still seems a little rough.
The first thing I noticed was that the boobs are a little robust. It's not an inherently bad thing, just I felt that you lost sight of her hips a little bit, and missed out on some extra curve. Deflating her lady parts might push you to try to find that curve.
Her shoes seem a little poofy, and they take up a lot of the attention that should probably be reserved for her face. While I did play around with them a little bit, I'm not sure if they turned out all that good.
I decided to forgo the mouth because I couldn't find a nice, low-profile equilibrium.
Pants and legs have always irked me, since in real life, you don't have such a harsh shadow below the knee and to the shoe. I've been fiddling with different approaches a lot, and I think I found one that works for me. I'm not sure if it's just my personal preference though, so yeah.

Her walk looks a little bit mechanical.

Not much change since you've got a great walk already, I just tried to make it feel more natural.
