Not bad
I see that you have a keen eye, and I didn't blam this since the point was indeed to show actual mistakes (I thought it was a parody at first).
One a side note, every Anime is made by a Team of Artists, you can't expect them to draw exactly the same, however the more they Draw, the better they get at it, thus the latest Naruto Anime doesn't have as many mistakes, and it's style is quite different then the original one.
