Aaah, Harry Potter - I have such a love-hate relationship with the franchise. I like the story, but loathe the ending, love most of the characters, but utterly hate Harry himself... So... it's kinda weird to me haha. Contrary to most people, the sixth Harry Potter is my favorite, and I like the movie a lot better than the book for various reasons. But the fifth book is SO MUCH BETTER than the movie - well, at least in my opinion! Anyway, I hope you'll like the books and that you'll find inspiration in them!
On a side note, now that I finally found a job, I'll be able to subcribe to your patreon starting next month, and I'm quite happy about it! Because of that, now is also a good time to ask you if you're actually doing commissions, since well, I'd love to ask for something once I get paid.
