This is a great painting, the only thing that bothers me is the red dot in his eye. I just think their might be a better way that you could manifest the symbolism. But still, the painting is one of the best I've seen of House.
If the red dot in his eye is supposed to depicts his "evil, smartass, whatever" side, shouldn't both his eyes be shining red. I don't think that's enough. He should have like a red glowing aura around hinself like Alucard or something.
i used the photo as a reference, i then painted it from the ground up using photoshop cs3 and my intuos 3 tablet, i dont like to use the real image in my work thats why i painted it from the ground up then added my own views on the image, im not good at doing photo manips lol thats why i paint it! the smudge tool is great for some things believe me i love it when blending colors (yes im old school hee hee).
