Take the high road and let it pass.
As these other posters have said - the juried shows can be a "stacked deck" with a "crap shoot" chaser.
FWIW, I very much liked the two color shots.
BTW: you might want to PM "naturephoto" here. He's a color landscaper here who also lives in "Joisey".
And also, "rteague" (Robert Teague) is a color landscape guy here who also runs the site that you will find in my signature space below. He "suffers" by having to live in Hawaii - but hey, not everyone has the good fortune to be able to enjoy Northeast US winters!
Oh, I think they both do larger formats than 6x4.5 but you might enjoy "talking shop" with them.
