Before I start this post I want to be clear that there's no intention of being critical of anyone in or out of the Exclusive Gallery, or of the gallery itself.
The photos posted by the OP in this thread fall into the general category of "landscape", so I'm going to stick to talking about landscape photography.
If you look through the landscape photographs in the Exclusive Gallery, you'll quickly spot some common characteristics. They are almost always shot at sunrise or sunset, or even at night. The ones that are shot during daytime are usually processed in B&W, or if they are not in B&W then they always include mist or dramatic cloud. Water is a common feature, always blurred with a slow shutter speed, and the processing style of all photos is designed to make it clear that they have an "artistic" rather than "record shot" intent. To be clear again, this is not a criticism but just an observation of some common characteristics.
So, to those who want to make it their goal to get into the Exclusive Gallery, the way forward should be obvious. Work towards taking photos that contain those elements above, and that display the same sort of aesthetic sensibility, and you might get in. Otherwise, you won't. And if you choose not to subscribe to the Gallery's particular aesthetic it doesn't mean that your work doesn't have quality, it just means that it lacks the particular signifiers that are expected in the sorts of photos that appear in the Gallery.
Before you submit a photo, ask yourself with blunt honesty whether it includes the signifiers that the judges are obviously looking for. I know mine don't, which is why I've never submitted one.
