I think maybe you are intending to make art? Don't. Adobe Stock is not a gallery. It wants technically perfect, normal photography, properly exposed and focussed, with good composition (and many other things), for use in adverts, business presentations and so on. You might be able to make art that is also technically perfect and that might sell well. (Note: don't bother with flowers though. Find original subjects. There are over 20 million flower photos in Adobe Stock already, the chances of selling even one copy for a new, perfect, flower photograph is very small indeed!)
