I'm not sure. There are very very strong elements here - tonal range, very zone system - but other elements seem out of place. What looks like fill-flash, which could simply be reflection from ground, feels out of place to me for AA's work, and a certain confusion from the vegetation likewise seems to be something he'd have avoided. Composition is strong, though perhaps not really an AA type of thing, and the perspective distortion is perhaps out of place too. All of which sounds highly critical, so i should add that I do really like this image, and think it works well for the challenge ... I'm just a hyper-critical kind of commenter :-)
Nice composition...hmmm, I like the way you darkened the top right sky to balance the bottom left. It brings my eye back into the photo and it stays there. I think I'll try that technique sometime!
