This is amazing. It must be one of the best Doctor Who artworks I've ever seen. The expressions, the realism, the colours, the feeling you get when you look at it - it can't be described in words. I wish I could express propersly how awesome this is, but all I can do is give it a humble try...
For once, I see art of the ten Doctors where they actually ARE the ten Doctors - resemblance and all. The colour works for me in a way that I can see what is in the past, what is in the present and what is a dream, or an alternative reality. The vivid colours of Rose's face come in complete opposition to both the sepia tones of the rest of the artwork, as well as the expression of true pain in Ten's face.
Truly amazing. I hope I find that book somewhere.
