Quite like the story. Being specific I find the Family History/Lineage fascinating. I read the oneshot about going to Hogwarts. Do you plan to skip to there of go through year by year till the eleventh year? I'd of course like to skip shad - because I like the idea of him interacting with younger kids in awe of him - while at the same time the backstory is revealed along with Hogwarts adventures. Finally to elaborate upon what I've liked so far - it is interesting to see Harry as a powerful lord with certain obligations and responsibilities in the future. That said one request - please don't make him go to America and learn Native American magic - makes for cliches and OCs. Also ianother aspect I like/look forward to is the ineraction of Harry with the Ministry/political system (it would be awesome if he doesn't suddenly appoint miggleborns everywhere or something but instead he/Potter supporters start reinfluencing the Ministry cuz they've been out of it for a while due to hiding). Sorry if a lot of this is about future expectations/direction you plan to take the story in. Its been a while so mostly I remember the part I liked - politics/positions (which you seem to incorporate quite a bit anyways) and wonder about how they'll play out in the future. (Here's my argument against OCs - since Potters are already powerful you can always establish ties/friendships from canon - Longbottoms, Bones, etc.) What about the Weasleys btw?
Stuff I don't like - grammar and spellings are the immediate concern ("Longbuttums" and wrong conjugations at places).
Great work finally and update soon!
