Instinct vs fiddling

My pictures are pegged on washing lines in my studio. Two of these pictures were reworked and four are untouched. When I enter the room, the fresh ones are striking, the reworked ones have turned into sentimental mush. Sometimes one needs to overwork and destroy to learn.

" The artist need not know very much; best of all let him work instinctively and paint as naturally as he breathes or walks. " – Emil Nolde

(The fourth and sixth ones are the fiddly effete ones, in case it isn't obvious.)
