Too blurry. Nothing is in proper focus. Stock customers expect highest quality images for commercial use.
Also Stock inventory contains over 29 million flower images. It's unlikely anyone will see much less buy your flower images. You should submit subjects that have less representation to increase your chance of sales.
Experiment with different focal distances and camera settings to increase depth of field. A narrow depth of field limits how much of your image is in focus.
