I don't know the character since I don't watch Lost, but I think the painting is extremely effective nonetheless. The detail in the wrinkles on his left eye shows that he has been through a lot of stress. His reaction to the stress is shown well with the quantity of white space. Normally I don't like their being so much white in a painting, but here it seems to suggest a depth of emotion that the viewer doesn't have access to--something so huge that it blots out everything else. However, in addition to the stress he seems to be feeling, there is also something about his expression that seems extremely determined. I think it's his mouth, how set and defined the curve of his lips is. Generally, I like the mixture of high contrast with the blood, and low contrast with the lines of his face and neck, which recede into the background. It creates more drama in a fairly empty space. You've been doing this long enough that I have no critique on your technique. Well executed as always, especially the neck, detailed eye, and ear-- the first and last because they are rendered with a minimum of lines but still look realistic, and the eye because of the skilled shading. Very nice, all in all.
I didn't really watch Lost, but this piece somehow told a part of the story nonetheless. Its particularly amazing how the wrinkles and colour have emphasized the emotion that you were going for. It also gives a hint of macabre into it. It contrasted beautifully against the blank, empty space left behind; it's subtlety really did add the charm into it, as if pulling me into the story. The other side of his face has left me speechless however: its quite the contrast from the other eye, almost as if a different emotion altogether, lifting the feeling of the piece-in-a-way.
I knew this was Ben when I saw this, first when I saw your piece "living in delay". Wonderful character, isn't he? And yes, about his eyes (it especially caught me when his daughter died). And his expression. You captured it really well! Your artwork is gorgeous!
I recognised him before readin anything! This is a great picture you've made! But then again you know your stuff. What can you say. What do you want us to say ? I can say that LOST season 1 and 2 were historical. I especially like the ending in the episode they had with Benjamin Linus were they put him against the wall and said that they found his parachute but also a dead body with his name. The classic benjamin Linus eyes shined up that moment.
