I get that consistency is a hard thing to achieve for an artist, even a talented mangaka, so I don't hold that stance too strongly in judgement but a strong part of me thinks that not acknowledging the more consistent ends at all and solely going with the most inconsistent value possible just because it's based on a pretty good method is a step backwards.
It produces some really awkward issues that we have to reconcile with.
Just to give a hypothetical example,
we get a pretty wide shot of the destroyed ruins of Konoha when Pain uses his Almighty Push on it. We can see Naruto and his giant toad summons appearing roughly in the middle of this crater, a bit closer to one side than the other.
Now, if we use the monument-to-wall distance in the calc that means if those characters are in the middle then the distance from them to the walls or to the Hokage monument would be roughly 31 kilometers.
Here is a shot of the toads and Pain facing off with the wall behind the toads.
Here is a shot of Pains in the same position with the Hokage monument behind them.
I don't think it would be hard to find rough measurements of how far each landmark is here from the characters, whether its to the wall or to the Hokage monument. If it's a lot less than 31 km then sure, you could say: "Size scaling is too difficult for an artist; it may only
look a kilometer away but based on a visual from hundreds of chapters ago that distance should actually be 31 km."
But isn't there an equally plausible alternative that these more consistent panels showing a lesser distance are the author's intended vision and his earlier panel that showed the Forest of Death
could be a mistake?
Because these aren't just one-off little mistakes. Kishimoto provides many such angles throughout that arc
here, and
here, and
here, and
here.
The argument that the author has trouble showing scale seems to work in reverse too; maybe Kishimoto can draw the features of the village really well up close but struggled to draw it correctly when he did the wide shot in chapter 115. We can't really say which version of scale he struggled with, but we can see how he consistently drew the village since that chapter.
Is
this not a significant portion of the entire village?
