Hello David - of the 13 images displayed I can say you have some very nice work, great technique and a really strong sense of compostion.
It's always a challenge trying to guess what judges are looking for. I know because I've been on both sides of the wall 
...I regularly submit to shows and also judge a couple of times each year for a photographic society.
But ONE thing that can always stand in your favor is the grabber. That's the image that stops the viewer in his/her tracks, and makes them consider the image before them.......wondering what it is, the aesthetics........whatever, but it demands attention as something out of the ordinary.
Ok - that being said, here is my .02. These are all good, and some excel over their neighbors. And again, this is only my opinion FWIW. Your 3 B/W images are nicely done. But I feel the trees/path is the strongest. You've got the intersection of the gentle curve with the shadows of the trees and the verical lines of the trunks. This is something people do not notice every day.
The close up of the cow evokes humor and whimsy. It is not your strongest piece, but if you can enter three it helps cover your "judging bases." It is a fun photo, and there is merit in that.
I think the vertical shot of the blue boat in the foreground is my favorite. It's landscape partner is very nice, BUT............... the vertical compostion gives the viewer a greater sense of depth, from the low edge of the life ring right up to that dark mountain top. The other does not share that and therefore has less impact. There's nothing wrong with that, but the vertical is more powerful.
The rural landscapes and attractive and would make wonderful postcards. The modern city stuff is ok. But I feel the others are far more unique. But you and I think alike David: we find a scene and compostion we like, and then we "stalk" that perfect time of day when we get just the right kind of light. I hope this helps, and good luck with the show . - Stu
