I’m pleased to tell you that I’m a design critic at pleasecritiqueme.com now, an online review service for web design. All the critics themselves are designers.
We are specific in our likes and dislikes, we are blunt but fair, we make suggestions and give alternative tips. This is our guideline.
Like Jared Spool says: What Goes Into a Well-Done Critique
Other critics are Grace Smith, Chris Spooner, Sarah Parmenter and many other great designers.
