Hi Ken. Very nice use of backlighting - it really shows off all the little "hairs" on the seed head. I, too, like the earth tone colors as well as the diagonal, off-center comp. I'm not sure if I like the circles in the lower background - on the other hand, I'm not sure if I dislike them either. This is very well done.
Good subject for a backlit situation, nice and sharp, colors are awesome. I think it would look better without that tiny bright hair on left. I like it!
