Sasori93... Your work had really improved... Keep up the great work!!
There's some shading I think they are missing... It's up to you to correct them!
But It's a skillfully amazing work!!
gah... im a little allergic to everyone calling kishimoto's drawings 'concepts' all of a sudden...
otherwise its okay, naruto's eyes have too thick lines around them though
edit: nvm the lines, the original was like that too... ^^;
