Hope I have a partner too.
Finally finished doing this wallpaper from something to nothing basis which means no stocks and scans except my pencil outline.
If you are asking where is Sasuke here are some options
a.) Sasuke is anti-social
b.) Sasuke took the picture
c.) Sasuke is at Orochimaru's place
d.) none of the above
BTW Tsunade and Kakashi are just fillers of the vacant space. (Why not place Sasuke there?... personal preference)
Hope you like my work. Photoshop colored.
I have tutorial if you are interested which is available in this [link]
