Let's see:
Face - The bottom left one
Jaw - Type 3
Eye Shape - Type 2 (depending on the look you're aiming it's different)
Eyebrows - Type 1 (like Eye Shape, can vary depending how angry you wanna make him)
Nose - Type 4 (all the same really)
Mouth - Type 1
Facial Features - chin beard, middle scar, right face scar
The rest is up to you, things like Eye Color, Hairstyle and Haircolor but a lot of combos can change your character a lot!
I can easily look like derplander just by dying my hair brown + his hairstyle.
hope that helps a little
