Adobe told you a reason, specifically, for the rejection. Please tell us that reason, so we do not waste your time with wrong suggestions.
The question @Test Screen Name asked you is important, as Adobe tells people why they reject pictures.
Yours have a
colour calibration white balance issue ( colour calibration to less bluish, warmer ...) and certainly the first one (the only one I looked in more detail) has also a noise problem in the darker areas.
You need to understand the standard
colour white balance calibration of your camera. It's done for the ideal picture with a certain amount of grey in. If the picture tends to the extremes (snow is extremely white!), the WB calibration tries to compensate for that, which makes the picture cooler than it should look.

Also, I would suggest browsing around some of the existing Adobe stock photos that are similar to yours. Remember there is a difference between a nice looking picture that is art and something useable for advertising and design. Something that doesnt serve a clear purpose for design or advertising is much more likely to be rejected, as well. Good luck! -Jyn
Your shots are too cold, there is a white balance issue - something like this would be better:
Also, you have quality issues:
Adobe Stock customers expect highest visual and technical quality. See links below.
