Hey I am new to Adobe! Can someone tell my why my image was rejected?

Too dark.  

The Histogram shows missing midtones & highlights, with considerable clipping on the right.  Those missing pixels are not recoverable, which makes this image unsuitable for commercial use. 

Great photos begin with proper lighting and camera settings. Night shots are very challenging even for expert photographers. 

Daytime shots are much easier, especially if you're new to photography. 

Good luck. 

Hello,

Composition and exposure are two big issues here.

It looks like you took this with a smartphone. Not so good for Adobe Stock. Especially night shots.

To get at least some success, you can't just take a picture with a camera/smartphone and upload it to Adobe. The image needs some editing/enhancing in photo editing software.

Out of focus, off horizon line, too dark...

What is the point of interest?

My best advice is to become way more critical of what you send to Adobe stock

Underexposed. There should be some detail in those buildings.
