I think the looking-slightly-into-camera thing works, personally, it gives her a cute ditzy feel; "Hey look at me going lalala"
Which is cute.
Stuff that bobs do that a bit un-smoothly; for example: Her dress would greatly benefit from some delayed bobbing, think jelly fish movement, every time she takes a step it goes | |, and when she starts to put down her other feet it gradually lowers with an / \-shape. I don't have a lot of time as of lately, so whipping up an edit might not be possible right now, but maybe sometime later.
Anyways, I really like it. Just touch it up and reduce all the copy-pasted-y elements and smooth out jaggies so you have a clean sprite in the end.
Oh, and do post other animations! <3
