This is a wonderfully stylistic design! I think the best part is how his entire body seems to be made up of these little things. It reminds me of some video game character with a lot of zippers or something on his body. You even showed a nice shadow. Or is that supposed to be the ground on which he's standing on? I'm not even sure if there is a person under there.
Even though there's no color, the shading is done nicely. It shows what you can do by combining pencil and ink. I love the idea of his weapon being a sword with an axe on the side. I can't tell if those are his eyes or holes. It's quite a new kind of picture.
