This is great! Hilarious, too.

Oh please... continue with this story!
I can never get enough of stories featuring a
“Cynical & sarcastic Harry Potter”
with the worldly disdain only a teen can exhibit.

yea loving it, I always found Harry a little too naive when encountering the wizarding world the first time. Like the intelligent cautious take.

Don't forget to spellcheck your author's notes too - yours contains "ahve", "i", and "imrove".
"Avatar" (the anime) first aired in 2005 - the first Harry Potter book is set in 1991, so the presumed reference is anachronistic.
The level of swearing is inappropriate for a K rating (suitable for 5 years and up) - I'd recommend increasing to K or T rating if you're going to keep using f*ck in your story.
Keep writing! It's a good story with a lot of promise. Don't forget to have Harry make mistakes - 11yr olds no matter how smart should be imperfect little beings. :)

A very promising start, well written. There's a couple of small errors to fix up (punctuation for dialogue, proper apostrophe use) but overall very good and they don't stop it being a fine and readable story. Congrats on posting your first fic! :)

Interesting story with lots of potential and believable development. Hoping he still befriends Hermione though

Looking forward to more :-)

Good start, for a first.
Here are my constructive criticism, I do not flame, I know the difficulties of writing a story.

I like the premise but I found the text a little hard to read. (The blocks of text seem condensed to me ...)

Separate your conversations from text paragraphs.

Personally, I wish there was a little more conversation, more context.

You have an idea in your head, a vision of the character, make us understand it.
Also, you could have explained where the story begins in your author's note.

Fortunately or unfortunately I know the original story too well.

All-in-all, this is really good. I think hashing through those grammar programs really paid off! I really appreciate; I love the Goblins! I can't wait to see what transpires next! Good one, author! Peace!

Harry does have a point there! Great job, author! Didn't get a headache reading this! Epic!

I feel this is going to be the start of a very very amazing adventure

Keep up the good work! This is amazing and I love it

Interesting idea. I just hope that your Harry isn't in Slytherin, as this would bring too much Snape and Draco Malfoy for the story. Maybe Ravenclaw? It fits with the disposition to question everything.

I always like a smart Harry story. This one seems like it will be good. One question, what house are you thinking of putting Harry in?

Amusing so far; keep it up!
