This is, by far, one of the best Doppleganger pics I've ever seen! I love the amount of detail in the linework and coloring. You could have easily just used a white lighting effect, but the blue really gives it a dark atmosphere that you would expect to see with this wretched character Great job with keeping the lighting consistent, as well. The line on the nose seems a bit off, but I like that the nose is done mostly with shading as opposed to a harsh line. Great job, and I look forward to seeing more from you in the future!
