No. We used to discourage it on the basis that artists will usually be biased toward their own work. There are some users that are still against them, but officially, we no longer treat them any different from any other upload. As long as it meets quality standards and at least one approver likes it enough, it will be accepted. You can search status:active approver:any to get an idea of what those quality standards are, as well as the approvers’ tastes.
