Hi! I will give you my personal opinion." The land " is third person singular. So, its the land belongS. If you were talking about many lands , then you would say "the lands belong to me", because it is third person plural. I think well DONE and bravo, have exactly the same meaning.
Notable is like outstanding, so I think it is more emphatic than great. Perfect and great is similar, but perfect would mean that there has been no mistakes. Hope it helps. Bye!
