Nice ^^ I always like Your colorings, and I have no ideas what's bad

but in that double page I think there are two 'small' things, which I think are not well done.. I mean shading:
- the big panel: noses, point/begining of the nose - I think that it's too dark, and Uchiha bros seems to be drunk xD
- the upper-left panel: it's really watchable to see the difference between the skin on face <dark>, and on left little side of neck - it's lighter, not smotth compostion between those two dark and light skin color.
Although, like always, nice work xD
