The colouring is great as always DD but there's sumthing missing in the pic if you know what i mean...I guess your job was just to colour it and that was done spectacularly.
I was thinking the problem is well the lack of emotions/expression on yamato and sai's faces (sai is excusable tho ). And I guess the focus is mostly on Naruto but i just noticed that he's the one with all the scratches and bruises but with a well done determined look about him. Yamato on the other hand is scratch free and basically looks like he's just standing there lol And also kakashi, I like the blood spot touch but he's just been on the ground and been smacked around a bit, so he should be a bit dirtier/scratched up.
Thats the only issue i would have with it though, give it a solid 9.9/10 As always, the colouring is AWESOME
