I have a better idea: You can go to UEFA.com section on UEFA EURO 2016 & there you will have photos for all players of all national teams, who took part in the qualification & will be in the Finals too (but only later, once the Finals' squads are announced). Would you be able to do the faces from there? I can send you my database with the teams' player IDs. Some players whom I don't know their EA IDs have started with IDs 260###
EDIT: Here are my previous posts with the rosters for Albania, Andorra, Armenia, Azerbaijan, Moldova & Montenegro

As you can see it shows all the subs & reserve faces/placeholders, but not the first XIs.
AM: Did you want to do the entire teams' minifaces? Or simply those which don't have them in FIFA16?
I'm happy to keep the original minifaces and just get the ones done for players which don't have them.
