The most important aspect of your work life is keeping an up to date and easy to read resume. Yesturday I received a resume from a 3D Artist. The layout of the resume was fine: work history, education history, self-taught education history, summary of skills, and a little more information about him. The guy seems to have worked on some interesting stuff, but he forgets one thing – URLs! Even if you don’t have a portfolio provide some direct links to rendered pictures, hosted on ImageShack or some other provider!
An employeer won’t sit down and email over 5,000 applicants and ask where are your pictures. If you don’t want to put the direct links in your resume then at least include them in your email.
