Your image is too large, pls resize. Concentrate on making the image interesting rather than the title, some have labelled their images "untitled" and their images have suffered no consequences. This is a plain, boring composition. You have not made use of lines on scene, they lead nowhere. Having just a lone petal on such a drab unhappening background is unattractive. If the interest is in the petal then consider moving it to another location for a better composition. That is allowed.
the use of leading lines is a basic tool of composition. you use lines to lead the viewer's eye.
in your photos case you could have used the lines on the floor to direct the viewers eye to the petal.
basic photography books will explain it better (and with examples)
