Perfume Puffin competition brief

for the front of my book cover for patrick suskinds book 'Perfume' i decided i wanted to illustrate an image that could look like a smell. obviously you cant see smell, so i found this a very challenging task. I thought it might be a good idea to use hair as smell lines as the girl in book who is very significant has red hair so i decided to experiment different ways i could manipulate the red hair to make it look like a smell.
