1st image is over-saturated, has chromatic aberration and blown-out highlights on some of the rocks - see where there is no texture at all on some of those rocks? The selective color effect in the second image is not something Adobe accepts as it lacks commercial appeal.
You can't correct these pictures because of the artefacts:
and the bad exposure: some stones have no structure left and simply clip to white.
In addition, your photoshopping is really of a bad quality, besides the fact that Adobe stock prefers pictures looking naturally and letting the buyer do the modifications that are needed.
Inspecting your pictures at 100% and 200% helps to detect artefacts, noise and other defects.
