While these images might look okay in a small size, once you start zooming in, the soft focus becomes readily apparent. The composition is also flawed, with messy backgrounds. As @RALPH_L indicated, Adobe Stock is already overrun with floral images, nearly 29 million, and yours would have to be technically perfect and unique to be accepted or ever sold. While it's fun and useful to practice your photography and editing skills on flowers, find more unique subjects for your submissions to Adobe Stock.
