Look at the histogram, especially the blacks at the left.

A histogram like this has a contrast problem, giving you a flat look. Adding a bunch of contrast, texture, and clarity will fix that.

Then you should see, if you can fix the chromatic aberration issue.

Like @jacquelingphoto2017 mentioned, your image is lacking vibrance and contrast.  I think the shadows have been lightened too much causing the posterisation in the shadows as seen below.

Hi @Max_03,

Too much of your frame is out of focus, plus it's underexposed and lacking vibrance.

You need to zoom to between 100 and 200% to inspect for flaws including that of exposure. If you focus was on the water droplet, then you should have zoomed on it more and bring it closer to you to avoid the blur in the forefront.

There's a link to a LinkedIn course here  that that will help you to improve your exposure. Also you can benefit from the list of what stock reviewers look for. 

If you have not done so already you also need to read up on the Adobe contributor guidelines and tips for getting your files accepted.

Best wishes

Jacquelin
