Dean,
Fabulous natural abstract. I think by rotating this you’ve actually increased the abstract nature of this.
For me, I have a mental block on the rotation. Very similar to my reaction to Paul Hetzel’s “Braided River abstract”. I’m sure it’s just my own perception, but even rotated as presented, I see a near/far landscape where the elements on the left are closer, and as you progress towards the right, it gets farther away. So mentally, I associate that with a horizontal near/far presentation. And I just can’t get past that and want to rotate it back to horizontal. I think all I can say is that it’s my personal problem… 
Love the abstract nature, patterns and the range of muted earth tones.
