Guys I need your help

as you can see from the top image Luke’s face is really Dark, no matter what I do I can’t bring the face details out.
so I had to replace it with a CG Luke… but im not sure if this was the right way to go, there is a point where I tried to Blend CG luke with real Luke, but I don’t even know if that works, the Main reason is, the HAT is slightly different and this is because I can’t seem to model it correctly…
if there is anyone that can help me with creating that?, that would be awesome.
I also don’t know if there are enough people viewing this thread to see if I need help here, anyway worth a try

Thankyou For reading

by the way, the CG Luke was ripped off from the Star Wars Battlefront II game. The Hat and Goggles were created by me in Cinema 4D, and it’s an awful job as I can’t model for shit

Edit -oh Yeah Roto Still needs cleaning Im aware so Ignore that Part
