I just realized an odd thing about my girl, she never walks with her tail fully flipped up. Either it's down, or maybe lifted pointing upward 10-30 degrees, but never fully lifted and rolled over on her back. Is this is a sign of some anxiety or past issue with her? Or do some husky's just not hold their tail like that? She also tends to walk with her head more down than I think other husky's do.

Husky tails really aren't supposed to flip over the back, (called a snap tail, is a fault) more like an elevated sickle shape. However the tail curls, or doesn't, is generally an inborn structural trait. A train held between the hind legs would indicate anxiety, fear or perhaps a physical problem. In my experience, their head when walking is carried more or less on line with the body. Unless chicken is involved than it's full up and focused

If spiders tail is fully up there is a mountain lion or lynx nearby. But it does the stiff flag. If its between her legs i worry. Otherwise not so much. And all 4 of my dogs carry their heads slightly different depending on build.

OK I guess shes normal.

Yup but if your worried post a video.
