Everything is straightforward and well commented, and you shouldn't have any problems there.
Maybe just a few notes:
Beware that Site Author serves as backup if article doesn't have Author selected. So, if you have Site Author field empty you can have an error when trying to view Article page.
If you choose links -- your "social menu" can also become ordinary navigation.
If you choose icons -- You MUST enter Platform names right as they are, to be converted to icons.
