First, what is a click?

Now, how much editing is acceptable depends on the type of image and what it is being used for. Photojournalists will often say that even arranging things in a scene before an image is taken is too much editing, never mind post processing (I've heard National Geographic requires RAW files to be submitted along with the developed images to ensure the integrity). In these cases most global adjustments are okay (exposure, for example), but things like the clone stamp or healing brush are not.

However, for pretty much anything that uses a model, particularly female models, it seems that there is no limit on what is acceptable. And certainly if you're creating something surreal, like a post-apocalyptic times square in NY, then that will take a lot of editing as well.

Also consider that most everyone considers a half decent picture to be AMAZING because they really don't know what they're looking at or don't know what to look for. If you want real critiques of your work ask other photographers or artists that know what good and bad really looks like and can tell you where you fall.
