How to find community feedback sites for web design and user experience critiques? [on hold]

One of the ways I improve my website design and good user usability skills is by looking at other people's critiques on websites. I used to like Concept Feedback but it has closed down.

How do I find similar sites?

(Please don't tell me to Google it. I did. I am trying to post this question in an acceptable SE Q&A format)
