I bet you macro on that first one would be AMAZINGLY cool. I like that shot in particular.
The second shot does to me what all nature landscap-y shots seem to do for me... which is leave me feeling like "Yeah, pretty... but not compelling?"
I think it's totally me though. I have some weird brain issues with nature shots. They just don't click. I should post a couple of mine and see if someone can tell me what the snark I'm doing wrong.
