1. Not in focus. It should also have been cropped further to eliminate the large fuzzy bloom on the left and the incomplete blooms along the bottom right edge.
2. Not enough of the bird is in focus, though the focus on the eye seems quite good. There are also halos around the edges of objects, perhaps signifying oversharpening or excessive processing.
3. Insufficient DOF, leaving too much of the bloom out of focus; harsh lighting contributing to overly dark shadows
4. Interesting bird, but his face, particularly his eye, is out of focus; there is also significant noise in the shadows
5. Neither flower is in sharp focus, but the left one is particularly soft.
6. Beautiful pair of cranes against a lovely soft background; unfortunately they're not in sharp focus. You may be able to improve this one with some post-processing sharpening.
With regard to flower images, keep in mind that Adobe Stock is already saturated with many gorgeous, perfect floral images; yours would need to be perfectly executed and unique to be accepted into the database.
2 and 5 may pass after a white balance adjustment. 5 may also need some careful sharpening. The other pictures are, I think, lost.
@default4ekle63oztxa I like the ideas you are trying but as @Jill_C has pointed out, you have focus problems on all the images here. Is this something you can see now that it's been pointed out to you? You should be aware of sharpness right from the start when you are examining your shots in the editing process. The sharpness of your images either have to do with your equipment or your technique. Maybe your lens needs calibration to get that focus at 100 percent accurate? Are you using a tripod? Sometimes you can fix the focus in post processing but it's better to learn how to get sharpness from the beginning. Keep shooting and learning!
Aside from the focus problems, flowers are a highly competitive category. Even if yours get accepted, you probably won't make many sales because the Adobe Stock database contains millions & millions of technically & visually perfect flowers. Wildlife is a better subject but it can be very challenging to achieve perfect results. Use a tripod, be patient and take lots & lots of shots at different settings.

Better luck next time. 🙂
