You might have a halo around some of the pedals. See photo 1.
You might, and this is really just a suggestion, try to make the photo more appealing.
I have had several photos accepted, and sold, by just cropping and changing the background.
I sincerely thanks you.
Though the roses are pretty, the composition is not very appealing. Too much brown dirt and too little green. A tighter crop could help somewhat. Keep in mind that Adobe Stock is absolutely saturated with flower images, and roses in particular. In order for your image to be accepted, or ever sold, it has to be stunning and perfectly photographed.
