Hi Thunderstone-

Just look at the definitions and use your imagination. For example you could do a picture of a different coloured flower in a field of flowers all the same colour,  or a bird wheeling silently in the sky. Another example could be a sweeping, empty beach or mountain range.
As I said the interpretation is your own, it can be as sad, serious, silly, funny or thoughtful as you wish.
I hope I've helped to clarify this, any further questions, please do not hesitate to ask. :)
