I could tell who it was right from the beginning, so well done. That being said there are a few things off a little bit (too much highlight around the top of the eye, and you lost his freckles during the blending process). Overall I still enjoyed the work, thumbs up.
For a 1st digital you did extremely well. I try to be more constructive and helpful in my comments, whenever I can. I think it is awesome people give others so much praise, but I always prefer for myself knowing if there is areas I might be able to improve. I am sure you will do even better on your next digital one.
