I wonder where those elements of this story, as you stated, are from, because I also recognize the character name and his... personality from somewhere.
A great first chapter, I will continue to be a fan of your works.

It was a disquise for Harry in the next-to-last chapter of my story 'Triwizard Redux'. A paragraph from that chapter also appears in this chapter as well.
