"This fine-looking, commanding man had become a shadow of his former self."
"a shadow of his former self" means he was not like what he once had been, right?
Then, I am wondering if "this fine-looking, commanding man" was fine-looking and commanding and his former self had been much worse before, or he had been handsome and imposing but then lost almost all his merits? What happened to this man first? Was his "former self" good or bad?
How can I paraphrase this sentence?
