Nice work would be an understatement
This piece is at a level of its own. Too bad some people judge things because someone chooses to use anime or happens to come from a culture that uses anime.
In my mind I judge content and yours is solid. Second story element which is both comical and semi-realistic. It does seem a little inspired by the Chuni exams in Naruto but much more action packed. Third the use of violence which is neither out-blown or ridiculous just plains taken cool. It's easy to watch and rather enjoyable.
Can't wait to see what else is hiding in that amazing head of yours!
