Very well done indeed! Reminds me a bit of Edward Norton in American History X. Good SBS as well.

Great job! Pretty seamless...just a little mess on the left, next to his neck.

good eye CMYK

There are two faces here?

Perfect! Totally seamless... He reminds me a little Vin Diesel. Maybe eyes are a bit (just a bit) small, but it's a detail. GL!...

you may want to use a different set of eyes, because the strange shape does not match the muscle structure very well, also there is a blend line above his left eye, the skin textures could be matched better in the area of the nose, and also you could use just a little clean up to the right on the old whiskers, and the blend line to the right of lips

Wow, it's hard to believe this isn't a real person. Great job!

Very nice work author...It looks like simple work but i am sure that was hard to match the sources this good...best of luck
