DF11 is a portrait style facepack that initiated production since October 2010.
The DF11 crew do release regular updates to keep their faces up to date as much as possible.
DF11 faces are 260 x 310 pixels big, which is (a lot) larger than default size (180 x 180), which you can see in the example below. In order to fully enjoy the DF11 faces you can download the exclusive skin panels, which increases the default player portrait sizes.
There will be special DF11 panels available shortly after the release of the new Football Manager game.
These panels will show the DF11 faces in their original big size.
Without these panels the faces will be shown as usual in game.
This is a stand-alone pack intended for use with Football Manager 2015.
DF11 faces will also work with any other version of Football Manager!
