Naruto's Lucky Day

In my opinion you have displayed the characters very well.

Dosu is perfect appearing to be identical to the character from the anime.

Zaku is well done as well, the visual effects do a good job of conveying his surprise. The idea of making him off model was one that could have backfired but you pulled it off well.

Kin is also very well done, after giving it a second look I can only find a single, if tiny, error. There is a break in her smile that doesn't appear to be deliberate.

As for Naruto, his facial expression is perfect, his clothes are nearly perfect, the blue appears to be a lighter shade but that's not a big issue. The only real thing that gets me is his hair, I can understand what you were going for with the lines in his hair but I just find them to be distracting.

As for the background, to my eye it appears you spent little effort on it, the grass was really well done, but the sky and tree need some work. Looking at this picture I get the felling that they are in the Forest of Death. The lack of trees suggests a clearing. Perhaps some background trees and a green canopy, would suit this scene.

All in all my friend, you do good work and I hope you continue to do so.
