Technical problems

There are a lot of artifacts and noise around your building tops and in the clouds.  I think the colour is too saturated and the silhouette buildings take up too much of the frame.

Remember to check your photos at 100%-200% magnification.  It is much easier to review focus, noise, artifacts, etc.  Take a look at the snippet at 100%, especially around the crane and antennas.

Regarding the colour, Adobe Stock prefers natural looking images which makes it easier for customers to apply their own effects / colour saturation, etc.

Here are some resources that you might want to review.
