I like this wallpaper.
It's clean, it's pleasant.
The vector is very agreable to my eyes, so accurate and skilled! :D
Also, the tittle - smothly correlated whith the boy pose.

I imagine it's hard to imagine a composition with this character (totally secondary, btw). However, the composition, imo, doesn't make much sense to me - unless I didn't get the idea/intention... :)
I mean, what does have the rainbow and the brown stick (*feeling stupid* don´t know how to name it! help?) to do with the boy and the idea suggested by his pose...? I didn't sense the match.

Anyway, it's a unique, inspiring wall of the awesome series Mushishi is.
(You should see the rest of the chapters! I bet you won't regret. At least, I didn't, it's one of my favourite shows, after Monster).
