Since this is one of my favorite anime series I just had to make a wallpaper of this sometime and with the 2nd season just on the way I finally got to it. (Although this wall isn't based on the 2nd season)
I basically picked a screenshot from the anime and created a wall of it. 
I tried different stuff on this wall and the final result became a mix of methods. Some tablet works, some pen tool action, some mouse action, some filter action... But I like the end result and I hope you will too.
And I think I got addicted to big-sized walls ^^ So here are the 2560 and 2048 version for those who share the feeling...

I like the simplicity. =) Also you did a nice job on the whole dark atmosphere (I like dark walls a lot lol). You could have added some stuff like grungy brushes or something to the bg though, but it's still a nice wall. And DTB is awesome on that note! (watching it atm^^) Keep it up!

I like the dark feel of the wall! I think you should've increased the contrast of the wall but it still looks great! ^^

It's kind of dark; my usual monitor settings displayed the entire picture as a black rectangle with a signature. ;) I think the lines for the right eye are a little rough, but everything else is fine.

I really like the whole dark atmosphere of this wall...The simplicity is a plus too! I never went past the first episode of DTB, but maybe I'll go back to watching it :)

AWESOME! i really like it. this wall is great! but i really wish you have added the blue outline around him just like how the contractors glow when using their powers! then it would make him stand out from the dark background! and i think that his eye colour should be brighter. brighter shade of red

This wall should become the new definition of awesome. Though I think the red in his eyes would give a more dark tone to the wallpaper if it was brighter.

This seems like to really reflect the series and the mood. Dark and mysterious. The font is also good - no-nonsense and to the point.

The text isn't annoying as it could be so that's definitely a plus. I like the screenshot you chose to vector and the dark atmosphere of the wall. It all fits Hei rather well.
