Very nice, love the comp on #2, personally think #3 would be more artistic if you crop out the top 1/3rd and get rid of the grass... The paint can really make these hills have a "painted" look. When I did this area and showed some prints, folks unfamiliar with it thought they were actual paintings, not that these aren't lovely, they are. I am thinking you had an overcast day... the colors are a bit more vibrant... had it recently rained? Nice shooting, love that locale.
I spent some time in the Painted Hills earlier this year. The hills are fenced off (for good reasons) and photographic perspectives are limited. Retrospectively, looking at my pictures, I like the tight and almost abstract crops a lot better. You did, in my opinion, a nice job highlighting the abstract nature of this place. Thanks for posting. Michael
