I've notice that you have accepted some of my submmisions (which was a total surprise) and wanted to know what is it that I'm doing right, so I can continue to do so. When others read this post they may think I'm a little off base.
Just a note: Adobe accepted your submissions. Not the people in this forum. The people in this forum can often help, but they cannot see who you are, check your account, or see your pictures.
What you must have done right is produce commercially viable photos that follow Adobe's rules. Usually people post their rejected pictures (max 3, full resolution) WITH THE REJECTION REASON for critique of how to improve. It can be painful.
Congratulations! When you get a refusal you may post here, to know what is wrong with that picture.
