no me aprueban una sola foto

1) underexposed shadows, soft focus and leaning verticals

2) focus on the bird is not sharp

3) lens or sensor spots (in the sky); not sharply focused; white balance is off (too blue)

4) nothing is in sharp focus and the horizon is not straight

Nice vacation photos.  But Adobe Stock is not a social media or photo sharing site. 

Adobe Stock customers come here expecting to find the highest quality images for use in their commercial projects.   Your images are not well lit and they don't have much wow factor.  As a customer, I just don't see much commercial value in any of these. 

Have you taken any photography classes?   How are your skills in post-processing with Photoshop and/or Lightroom?
