A good effort Bambang, with only minor errors, so you would communicate what you want to communicate. Corrections as follows: "It's been a really nice conversation, I've enjoyed talking to you, and hope we can continue again later." A bit more natural would be something like "It has been a really interesting conversation. I've enjoyed talking to you, and hope we can talk again soon."

Keep your tenses the same throughout the sentence. It (has) been a really nice conversation, I have enjoyed talking to you (and I) hope we can continue again later?
