In no way am I referring, accusing or otherwise alluding to Amy Jo copying the style of AA. Both her and their work travel separate conceptual roads altogether, but the general aesthetic of the source images, degradation of those images snippets, color palette, plus (as you mentioned) the explorative and organic overprinting ends up with a similar look.
To avoid sounding like a complete wanker, I took another glance at AA's Explosions in the Sky poster, the one that came to mind when I first took a look at this. I am going to stick by my statement.
It's a beautiful poster. Just one of those "could have sworn it was AA from the thumbnail" things.
