Been waiting patiently for and can now happily order this together with Part 1 as it's now part of their "2 for GBP 25" promotion
EDIT 10/8/16:
Both arrived yesterday and really like the artwork on Part 1.
Not sure about Part 2 because the head of the Titan and the background is mostly blurry with the human standing out in sharp relief against that image - all just a bit weird,
