So, based on the feedback here and elsewhere, and due to the cover artist saying I shouldn't use his layers in any cover I make on my own (the third cover above), I've tweaked the second version, which most of you preferred over the first version. I think this is the final version, although I do plan to rotate through various covers and blurbs over time. Data data data. Yum yum yum.
But this one is the official cover to start with.
