I've said this many times before, but this seems like a good place to repeat it:
If you post photos of your work on a public forum, that work is fair game for any other member to comment on... positive or negative.
If you are the thin-skinned type or can't accept anything other than "attaboys" you shouldn't be posting photos of your work in the first place. To post photos, and then to get upset or "offended" if someone says something that doesn't meet your expectations, is unfair to all the other forum members.
