Sprites into paper miniatures for D&D

[Previous]

Most notably is the selout (usage of different outline colours), some outlines have much less contrast to the inside pixels than others (for example, compare the first one's arms and hair). The light source isn't too obvious either and some parts even look pillow shaded (second guy's closer arm). Generally, the colour contrasts could be more even (fourth guy's body, little contrast between the two brightest shades, quite high contrast to the blueish inlines).
