Thank you for the advice, it's sincerely appreciated. Writing this also made me feel better.

As advised, I looked up the juror for this exhibition - he's a photographer, no landscapes, just portraiture, and parts of his website do not work. I am not sure what makes him qualified to be a juror--perhaps it's who you know?

As was said, from now on I will try to determine who the juror is.

I am not naive, but galleries should specify the genre if they are locked into one, otherwise they are just looking to collect as much as they can from as many artists as possible, knowing they will never consider some of the submissions--that's unethical. But from first hand experience, many of these galleries are living hand to mouth--but that doesn't make it right.

This was a very cheap lesson, I wish they were all this inexpensive! Guys, thank you again!
