Viggo Mortensen in The Road

This is a rather quick photo referenced pencil drawing I have done today.
It is based on the film The Road where Viggo plays the nameless father. I think it is a very well made film, though rather depressing.

It took me roughly 4-5 hours (and yes I do consider that quick)
I think the original looks better than the online version, but well. I am also not entirely happy with the similarity between the photoreference and the drawing, but I guess its ok for 4-5h.
If anybody has any tips on how to make pencil drawings look good online, that would be very much apporeciated.

material:
A4 paper
mechanical pencils (HB and 6B)
graphite powder
charcoal
kneaded eraser
