Start with facial grid. Pupils align with edges of rested lips. Corners of eyes align with sides of nose.
Average face is 5 eyes wide and 7 eyes long.
Begin adjustments measuring your own eyes to check the distances on your face.
Pay attention to your facial bone structure..is your face long or round? Do you have high cheekbones?
Your ears are longer than you think and start at the eye line and end at the nose line!
Don't like your facial expression that is relaxed...switch it up but remember if you smile then your features changes. Pay attention to you eye and checks for laugh lines.
Once you feel like you are looking like yourself, begin adding values!
