Well... the reason of why they are all angry is because you've been building them a la Mr.Potato, and you only made one pair of eyes (and edited slightly so it would fit)
.
I think the new sprite (the woman) doesn't fit that well.
The highlights on the hair makes it stand out in a weird way and the dress coloring looks way softer than the mages' robes.
But leaving that aside, I think you could fix the face, she looks cross eyed and the lack of nose is just odd.
So... I did a fast edit to show what I would change.
Also, those triangle things coming out from the back of her arms, don't really look like shoulder pads (or whatever they are supposed to be, so yeah playing with that might help.
Overall nice, hope you start pixelling more.
