rechazo de fotos

Please indicate the rejection reason that was communicated to you by the Adobe Moderator. Here's what I see:

1) The swan is not in sharp focus

2) The entire tree trunk is not in sharp focus. The vertical background elements need to be straightened.

3) The horse doesn't seem to be in sharp focus, and is rather underexposed. The  image has a white balance issue, a bit too blue.

4) Needs to be straightened and cropped tighter.
