Eh eh. I don't know about Ansel Adams, but I sometimes find images unpleasant as they are too full of pointless detail indeed.
As with many of my photos, the subject is more the ambiance than a particular thing, if there is a subject, a criticism I frequently receive. I was fascinated by the mist (actually clouds going though the trees in the wind), the light, the stones and lichens, the romantic trees, the weeds, the fairyland sort of atmosphere, hm, did I miss something? :-)
Excessive detail in a landscape photo? I wonder what would Ansel say ;-) I'm not sure if you had intended to have any kind of "main subject" in this photo, but for me the part that draws my attention most is the bright area in the middle. Thanks to the mist, the quality of light on the stones and the greenery beyond is very interesting.
