It really is beautiful.  I'd love to see him animated.  

Thanks for the comment.

I wanted to draw this drawing without details, it seemed to me that it would look more beautiful.

I agree that the poses are very good. I love the bottom left pose from below.  He's very menacing.  The sword itself is a bit flat, but I know it's just because of the low colour count.  Maybe some dithering would do it some good?  But that may not be your style, so don't listen to me!   Overall, I think it's great!  

He looks cool. The poses are also quite good
