My suspicion is that for some sprites, for instance on clothing and hair, you are not using a 1 pixel brush of solid colour, but transparent brushes/burn tool to add darker areas to a sprite? Sprites should always be done with 1 pixel solid brushes. Shades should be picked manually and applied in the same fashion.
Some parts of your sprites have these issues, while others do not. For instance, Azura's face is just one pink, as it should be + 1 darker shade. Azura's hair has more than 8 colours of blue, but really only 2 can be detected because they are all so similar. From what I can tell, you created the darker "shading" on the hair with the process described above.
