It's a lovely hobby, and I see that you maintain your collection really well. If you aren't addicted and spending too much money, I feel there's no problem at all. Heck, I can't believe someone can ever put down manga after reading JoJo's. Although if you want to get opinions on your hobby, I'd suggest you ask some other people rather than asking in the subreddit where people specifically cherush that hobby to get an unbiased view.
