Cover Look-a-likes

I popped open an email from Houghton Mifflin Harcourt this morning and found these cover look-a-likes.

Obviously, they aren't identical like some cover look-a-likes, but they are similar.  The close up image of a crow, wings extended, bleak gray background, and an accent touch of red.  I like both of these.  I like the cleaner lines of Six of Crows, but I think the messier look of An Inheritance of Ashes gives a much more frenzied look to the cover, conveying a much different mood or tone.
