How this image can look better for stock?

Also not all my recent pictures are displayed on my public profile.

Hi @Diana_Marinela,

As @Nancy OShea said, there is a bug in the forum software, that makes it impossible to view the original posted image, only the preview. So, I suggest, you attach your pictures so that we can correctly analyse the asset.

Hello,

I also wouldn't spend too much time on this for stock. There are gazillions of flower shots, so the chances of a sale (and consistent sales) are very small indeed.

A very important question to ask yourself is who will buy it and why? What could it be used for realistically! 

Is this a full-size image? When I zoom in, it appears quite pixelated which gives the impression that it's not in sharp focus. It's also over-saturated and a bit underexposed in the shadows.
