Others will be able to see the critique and comment on it providing a conversation and dialogue between the photographer (who can participate) and the viewers.

An emphasis on the rationale would likely be useful. I’m hoping that by providing some ambiguity, as well as designing these critiques to be ‘serious’ that criticizers will indeed rationalize their critique within the commentary section. Whether or not this works well has yet to be determined.

Thanks for the comments!

Suggestion:
To me it seems like you are asking for the photographers to give a laundry list of good and bad, and then follow it up with “commentary”.

Perhaps an emphasis on the rationale of the critique might be useful.
