This story has been pretty good so far. I think that the first chapter is a little cramped. I think there might have been too much info in it. But I think if it had been stretched out a bit more and it would be excellent; just a friendly suggestion.
McG was pretty calm about him doing advanced magic. Are you going to put Harry in the same house? I think Ravenclaw or Slytherin might be good. I hope Harry and Tonks are friends and maybe more later. I can't wait for an update so keeep up the good work.

I am already following in the footsteps of two fanfictions; one that I have read that has Harry and Tonks in Ravenclaw, and then other has Harry in Slytherin with Tonks in Gryffindor. They are really good fics but they have Harry to dark. I am going to follow the original story as well as I can with my few little changes. I am currently having trouble-fitting DH to fit with my changes so I might end up doing something completely different for the last book.
As for McGonagall she was just stunned. Also as a laid-back guy, I have a hard time seeing through Professor McGonagall's eyes. Maybe I should have made it Flitwick; he is a laid-back guy like me.
I do plan on having Harry and Tonks be pranksters to rival the twins so if you have any good prank ideas I would be grateful.
