i gotta agree with a101 here, shadows crit wasnt a crit at all, ill explain why
its common practice to only build half a model and mirror it over for the other half, as he did here,
just showing the half of the model built wouldnt show his proportions very well, so he mirrored it over to take the picture, without welding the vertexes to save time, lots of people do this, (myself included on occasion)
most people, (hopefully) know this, that has nothing to do with the shape of the model, or any proportions, and it wont be on the final model, calling that a crit is truly newbie,
--------
now the model, it is built very good, but it doesnt look like naruto for some reason, the proprtions seem to be about right but the look of it isnt very naruto ish,
possibly a skin could fix it, but i dunno, ill name a few flaws on the model which could be causing it though,
bring out the ears a little more to the sidesfrom the front view,
lower the armpit just a tad,
and poof the pants out a little bit, thats all i can think of,
