Doctor Who - Cybermen

Before getting to deep into this, I want to make it clear that I am not an artist, but a musician. What I like most about this work is the detail on the nose, specifically the imperfection of his face; this and the tension in the face and neck very much reflect the guilty anger of Tennant's take on the Doctor.
The image of the Doctor in front of Cybermen, lets face it, has been done a million times, and while I love the posture you've given him, the limits of the chosen subject prevent any really great vision from being realized.
While I say these things about the chosen subject, I am extremely impressed by how you executed. The shading and shine on the Cybermen is absolutely stunning, and the details of the face neck and figure of David is superbly done and reflect his time as the Doctor.
