I've finally been able to make some time to start in on the blue. The bottom left image is the only one that does any justice to the transitions - but the top left does a fair job of showing the three layers of blue that I used.
I'm.... reasonably pleased. Barring feedback to improve the blues I would consider his right arm and helmet finished. Of course it's likely that I'll come back and change this entirely when I start work on the rest of the blue and wind up happier with the newer sections. That's the curse of painting in shifts though.
