No sure about the landscapes to be considered pixel art, but it sure looks like good pictures.
And about the pivot animations, I'm glad this type of method fainally can be expressed with such characters.
I used to see it in very cartoonish characters, and it particularly looks good in these 2 exemples, particularly the red head girl.
I will concentrate on this particular red head girl since the other one is not really pixel art to me.
She looks very good.
Even if there is some flash-animation-feeling that can take me a bit out of it. (arms and shoes mostly getting very lifeless)
Beside of that this is very gorgeous!
