You submit it for approval (like you've just done), and then an editor checks it and either approves it or sends it back with changes needed. In this case changes are needed, the media license (CC-BY-SA 3.0) isn't mentioned in the license file (which only has LGPLv2.1).
I am new to the author side of ContentDB, how does the approval work, and do I need to do anything more?
