A Letter Bee - Lag Seeing

Tegami Bachi- aka Letter Bee
Set in a world of perpetual night, the only light seen in this cold world comes from the artificial sun at the center of Amber Ground. Lag seeing is an new Letter Bee charged to deliver anything and everything with their sender's "hearts". Along with this task he seeks his old mentor and solve his mysterious disappearance.
Story wise, the setup is an interesting one. I personally like it for the mellowness it has.
My doodle wise... I got bored and thought it would be interesting to doodle him-- since there is a little fan base on this manga.
