Minimalist Sunflower Isolated Colour Technique

Very minimalist in nature, a sunflower with yellow petals and a dried sunflower head as a pair. I manipulated my original photograph to create an isolated colour image, with the petals of the one flower remaining yellow while the rest of the image is a monochrome of greys. The flowers reach into the white background of the panorama style image, from one side.
