typically photo contests will describe what they are looking for, or if not, the title often will give you a clue. like..."forgotten places" or the description will add things like, images that represent "power" or Energy or whatever. Read into the contest description let us know.
I do like what you did with the lighting on several of them, liket he moon over the opnd and the sunset on the trees.
I really like the ones that show the clouds and "virga" (rain falling but not hitting the ground). They're all good, but those captured a really cool event and are composes well too. I think they are the first and third pics in the second batch you posted.
I like many. But I'd have very specific input on each so lets get by phone this weekend.
Thanks Tim!another vote for "moon over midnight pond."
good stuff, Perry.
For the category you described i like the last pic in the first posting. The sun and clouds are a climatological feature. If this is what they are talking about. Nice shots Perry.
