Mr.knightley seems is a middle-age man.Two things can tell us that one is his hairline and then is his wrinkles.He has brown with sienna hair.His bangs is little curl.But his smooth skins and the beaming eyes marks his good health.He wears a black coat and tie a milk white cravat.And he sits in a full with candlelight room.The delicate partern of the wallpaper tells us that the man maybe is a royal person or the high-status. 

His eyebrow is raising infroms us his curiosity and surprise.He is likely to looking at someone who can catch his eyes.His brown eyes twinkles with love and gentle.His nose is little taller than others and it is like bull's nose.His well-defined thin lips,like two lines going from the sides of his nose to the corners of his mouth.It's signs his strong will.Maybe he is ready to face the problem.

All in all,he is a handsome,polite but courageous man.
