I try not to be annoyed by any criticism. I'm not 100 percent, but I try.
Ultimately, a piece is intended to be viewed, and is intended to move the viewers. It's not fair to discount any viewer's take on your work, if you're being honest. If the take is 'it sucks' or 'you should have stood 10 feet left' well, that's how my photograph took one viewer, that's information about how my work is succeeding or failing to connect with that viewer. If all 20 viewers all have opinions that I should have stood there, or zoomed in, or out, then the damn thing is probably framed wrong. If one viewer tells you the white balance is off, and 100 tell you the picture made them cry, well then you've maybe you've succeeded. That doesn't mean that one guy is a weenie or wrong, it just means you didn't connect properly. Maybe next time you should get the white balance right, and see if you can make 101 viewers cry, instead of 100. Maybe not, it's your choice.
The point is, if the work isn't for viewers, who's it for? If the viewers will take the time to say something, anything, be happy, meditate a little on what they said.
