If you liked Tintin and long for more comics of the same kind, I recommend you to try Blake and Mortimer. They're different (e.g. with a more serious and wordy style, hardly any comical gags, but also with more fantastic elements). But they are the closest I know, and in some aspects even better (I personally prefer them although I'm aware it's due to very subjective factors, most people would still rank Tintin higher overall and Blake and Mortimer don't have such a universal acclaim).
The only thing I dislike about the post is the gratuitous rant on AI at the end. It is great news that Tintin joins the public domain. Especially great because it's one of these cases where the owners have been especially abusive, chasing fan efforts done as a labor of love, lest they harm their sales of overpriced merchandising.
Why exactly should be worry about people generating AI images of Tintin? What is the harm done? We know what the original albums are, they will probably be preserved as long as there is human civilization (despite copyright, not thanks to it), and we can freely decide if we also want to read/watch/see derivative works (and which) or not. I just don't see the problem at all.
