I know everyone hates twitter, but if you have an account and you're looking for work, now's a good time to join the #PortfolioDay tag.
Pick 3-4 pieces you're proud of, that represent the work you want to do. (I.e., if you're an aspiring character artist, post characters. Don't just post environments.)
Make sure to actually say what you want to work in, if you're available, and where clients can find you IN your tweet! I.e., email, portfolio site links, etc.
Good luck, everyone!
