Good start man. If you want I can propose some adjustments.
I think the anatomy is off a bit. I did some paint over to try to fix the issue. Take what you want
1- The shoulders has been modify
2- The nose and mouth did match Affleck anatomy
3- You were missing some forehead and hair volume
I didnt fix the iris. but they are a bit big

Good one mate.
The helmet is not big enough but the rest is spot on
