Loved Anna Karenina. Where to go from that?

Hi, I’m here because I wonder what I can read after Anna Karenina. I loved the way Tolstoj approaches and describes his characters in this book, specifically their thoughts, and I loved how human and dislikeable they are.
I thought about getting some of his other works but most people say this is his masterpiece so I don’t know – it’s the only thing I read from him.

Recommendations? Doesn’t necessarily have to be classic russian literature but I do enjoy the historical aristocratic thingie – I would also appreciate something more modern/contemporary though, as long as it has human-like characters
