outlook, look, appearance, condition, view
觀 centers on the act of looking with attention: observing, viewing, or examining something to form an outlook or assess its appearance and condition.
觀 combines 雚 (a type of bird, likely contributing sound) with 見 (see), suggesting the idea of looking or observing. The modern Japanese simplified form is 観.
A bird (雚) perched high up, using its sharp eyes (見) to survey the landscape below—this is the act of observing and taking in the view.
For カン, imagine you can see everything clearly through a pair of binoculars: can -> カン, and you observe the whole outlook.
