More contrast is usually good at GD. But I like the muted natural tones you have here. I think the face could use some more contrast, and maybe the horns. The blade needs to be straightened, and the metallics could do with a brighter highlight or two. The weakest part of the mini, for me anyway, is the corpse in his hand. It needs a few more colored washes to help add more depth to the shading. And some gore, maybe. The real highlight for this piece, the most beautiful part, is the base. It is very well done. Overall, it is a very nice piece. Well done, I hope next year you bring an even stronger piece, as you are well on your way to a trophy. Keep at it!
