For art directors to get the very most out of illoz, getting an account here is a must. Projects can be taken from start to finish, right here at the site, from viewing sketches online to downloading the final art. More details about that here
Because art director accounts at illoz provide access to a confidential area of the site (that portfolio owners do not have access to) it's neccessary to either receive an invitation from an art director with an existing account, or to apply for an account.
You can learn all about the various services for art directors and also apply for an account right here
