I choose to be really accessible for a lot of reasons. One result of that accessibility is the inundation of critique requests.
Unfortunately, there’s just no way I can critique the portfolios or websites of everyone who asks.
The best advice I can give for getting professional and/ or experienced eyes on your work is to build relationship and add value.
Join Twitter, the blogs and the other communities where these professionals hover. Respond and comment. Be helpful and answer questions, provide recommendations, encouragement and never pester them. That’s how you get on the radar.
After you are really on their radar, you can build a real relationship with more of the same and eventually ask for a friendly favor – a critique.
It takes time but so does becoming a good artist.
Also – look for the artists who are good but less-well known or who have less people asking them for critiques. Any artist that is better or more experienced than you will be helpful in your creative journey.
…and it never hurts to just send a brief, personal, polite, well-written email with a link to your site… …maybe you’ll get lucky with perfect timing!
