This is a pack of 6 heads (faces) for Niko, done by me, Driver097:
1.Niko with more mustache
2.Niko with more beard (and mustache)
3.Niko with NO beard/mustache
4.Niko with "goatee" beard
5.Niko with mustache
6.Niko with edited beard

You have 2 ways of installing it:
0. Take a backup from the Below-mentioned file!
1. Copy the "playerped.rpf" to: game directory\pc\models\cdimages
2. If you have other player-related mods (for example a mod that changes Niko's face) and you Don't want 
it to be removed, you can manually open your original"playerped.rpf" file with OpenIV or other similar programs and 
import the files which are located in the "Files" folder to the "playerped.rpf" file.

Any suggestions are welcome, and please note that this is my first mod!
