I was watching a video by a wildlife photographer that I have been following for some time now, Simon d'Entremont from Nova Scotia. ( https://www.youtube.com/watch?v=z8i7k8Rj694&t=52s) He mentioned another YouTuber James Popsys ( https://www.youtube.com/watch?v=hH9VBrx3rnY&t=133s). I checked out Popsys' channel and he was talking about how to draw people's attention toward a subject that you want to be the primary part of your image. This daffodil has white petals with a yellow corona, so I used a white vignette to subdue the white petals, leaving a hint of them showing.
