There have been several different requests for photo critiques on photo.stackexchange.com. In the past, we (as a community) have generally not been inclined to allow critiques here, as the Q&A style doesn't really lend itself to a good discussion which is really necessary for a subjective topic like this.
We now have a chat room, which means we have a great way to discuss more subjective topics. In order to meet the requests, there has been a discussion there about having scheduled critique sessions.
Since this is a global site (many time zones), we're going to try scheduling sessions at various times and see which work well. The chat room scheduled events are posted, so check in occasionally and try to attend if you're interested.
Eventually we may have more regularly scheduled sessions, but this is a new process and it will take time to figure out.
