1) the entire leaf is not in sharp focus, and you have blown out highlights and noise
2) same issue, but almost nothing is in focus
Take a look at the more than 14 million images that are displayed when you search on "green+leaf" in Adobe Stock. That will give you an idea of the quality level that Adobe is looking for; it will also convince you not to concentrate on such an over-represented subject for Stock photography.
thx for response,
i see lot of picture with saturated color, maybe if i apply a post prod filter it will be better (except focus problemà
many thx ?
You can't fix the focus problem, and filters are not desirable. On this page, Adobe specifically says "Don't Use Effect Filters".
And as I said earlier, given the millions of images already in the database, even if you could overcome the technical problems with these images, it is very unlikely that they would be ever be seen or purchased by a Buyer. Shooting plants, leaves and flowers is a good way to practice your photography and editing skills, but I wouldn't recommend concentrating on those items in order to make sales. There is simply too much competition.
