There are several options you could consider. The most direct would be posting a move request on WP:RM in the Uncontroversial moves section. Make sure you mention that there has already been a discussion on the talk page (Provide a link to the section so the admin doesn't have to search for it) and that you would like an administrator to review the discussion.  If the admin's or another editor move it out of Uncontroversial moves, you'll probably have to restart the discussion using the process described on WP:RM.
