I submitted these two photos to Shutterstock last Friday.  Both were rejected for
Focus- the main subject of the image not in focus,
and Exposure - the image being extremely underexposed and/or overexposed.  
The Fall Road for also having excessive noise, film grain, compression artifacts and/or posterization.
I need to learn more about my camera and photography.  I believe I understand Shutterstock's review, and now need to learn more about my camera and how to correct these issues.
