Required criticism of photo

As already stated. the photo should be color and watermark is not allowed.

In this case, I think it should also be mentioned, landscape photos, especially bridges, should be in panorama format. Line your objects up on the Rule of Thirds. Make your photo interesting. 
 

Thanks everyone for the feedback & guidance. As a beginner photographer, I'll keep these things in mind in future.

...recommended improvements?

• Get better equipment.  Start saving for a good entry-level camera, lenses & tripod -- new or used.

Read the Stock Contributor Guide.  Adobe Stock customers expect the highest visual and technical quality for use in commercial projects.

Hope that helps.  Good luck!

Bring back the colour, correct the exposure and delete the watermark. But even so, the picture won't pass because of the washed out details.

In the context of Adobe Stock, Adobe rarely accepts black and white.  Color appeals to a wider audience because customers can convert it to black and white if they wish.

Even though Adobe usually doesn't accept black and whites, I have some in my portfolio and they just don't sell.  In fact, I've only ever sold a few across all stock platforms.  I don't waste my time with them anymore.
