I like that first one especially, Julian. So simple yet so rich in detail and interest. Have you heard the expression "sometimes you can't see the forrest for the trees?" That does not apply here.
By the way, I shot a few shots into the sun and also with the sun at an angle to my front (not unlike your forrest shot above) with the DP1 and got a very distinct greenish/blue flare spot lower middle (or thereabouts depending on the angle the sun was coming in at). Have you experienced this phenomena with your DP1? (I almost expected to see it above.)
