His eyelids appear unnaturally swollen in the first photo. So check several photos of him before spending too much time on that "sleepy" look - it may not be necessary.

What jumps out at me is his overall Irish or Scottish look. He has that classic "Bay City Rollers" face. So you might use something like this as a starting point:

I did that modeling a real-world female who had a Scottish maiden name, using the Scottish Female Face as a starting point, and it came out surprisingly good with some tweaking of the morphs against reference photos.

For the same reason I would find some reference photos of his profile online, since the size/shape of the jaw and nose can be defining characteristics for Irish/Scottish faces.

Likewise, his teeth are unique. So if you'll render him open-mouthed I'd spend some time trying to match the teeth and gums.

Lastly, try not to let his facial hair distract you - focus on the shape of his face, and you can easily add that facial hair when the face morphs are done.

Good luck!
