Smile (Sir Charles Chaplin) - on piano

ok, I made a small mistake (or more) :-) Please comment. I know it is not perfect. But, without your comments how can I make it better?! And here is the nice lyric by John Turner : Smile tho' your heart is aching smile even tho' it's breaking when there are clouds in the sky you'll get by if you smile through your fear and sorrow smile and maybe tomorrow you'll see the sun come shining thru for you. Light up your face with gladness hide ev'ry trace of sadness altho' a tear maybe ever so near that's the time you must keep on trying smile what's the use of crying you'll find that life is still worthwhile if you'll just smile.
