What a cute little guy. The blacklinings seems a little too stark on the white skin, especially since the wings and and face are handled very subltly. The teeth and axe hilt might have benefitted from being shaded differently from the skin to make them stand out better.
I love these miniature familiars from the Confrontation line. Mini looks solid, but seems a bit drab. Maybe some deeper shading on the feathers to bring out the wings.
