Then there are the compositions that are composed solely of a detail or details. Often I look at the details of architecture and think "That would be so perfect on its own." In fact, the are parks and gardens specifically devoted to showcasing details of former structures. These are wonderful treats for the eye. Too, antique shops frequently have doorknockers, mantle pieces, wrought iron gates, carved doors and a host of other remnants in wood, metal and stone.
So if the details are best left out, find another way to create with them!
