The one thing that really sticks out is the fact that under the robe is white. This area would be so in shadow that it would appear mostly black. The white 'betwen his feet' looks odd. Other then that, pretty great job. The nmm chain I thought was metallic.
Really nice job on the NMM technique. Overall a really clean paintjob. I think the only thing keeping this out of the 8+ range is the white robes and freehand around the face. They look good, just not as good as the black armor and NMM effects. Over all really nice work. Congrats.
