Are these sentences all OK and natural?
(you are telling bad things about something, economy etc.)
If I say,
You have drawn a bleak picture.
You have drawn a gloomy picture.
You have drawn a pesimistic picture.
the first two are fine - the third doesn't sound quite right. I think we would more likely say a 'pessimistic view' rather than picture. (Note: 'pessimistic' has 2 x ''s'')
