I understand what you saying. I looked at the photo a long time and the bland sky kept irritating me so I added the cloud. But the moment I did that I got bit unsure of myself and posted here to get advice from experts.
If by "experts" you mean expert photographers, forget everything I said. If you mean expert at having opinions, then mine are still valid.
+1 on that regarding myself also.
As said, it comes down to what you will use the picture for. To hang on your wall or sell prints, then no problems at all. Even for publishing I would say, depending on which context.
Again Sanj, thanks for starting this thread it's important to have a philosophical discussion about what we do also.
