Before I offer suggestions let me say that your work shows a lot of potential and a keen eye for expression. Even where there is room to improve I think you have a very clear picture of what you\'re trying to accomplish.

Again, great work on trying to capture expression in the face. Overall I think there\'s not enough distinction, however, between colors. I cannot, for instance, differentiate between what appears to be a beard and what might be chest armor.

Same problem with distinction on this one. Consider using a different color for the cloak/cape. With the detail on the cape consider using a color only slightly lighter than the base if you cannot get the lines thinner - this will help blend the detail in with the background a bit.

This one is hard to comment on for me because it lacks a lot of the detail you\'ve given your other work. The paint is also very thick, which washes away any expression or highlighting.

Good work and, again, great facial expression. The colors on this one are seperated well enough to be distinct as well. Some of the highlights, such as the elbow joints, are a little too harsh however - consider making these a little closer to the base color to assist with blending. Consider also going back to straighten some of the thin lines, such as the white \"belt\" on the waist, by using the brown of the fur to conceal the smudge.
Overall good work and good progress, especially as you get in to the last miniature. Keep it up!
