@susie1205 - You will one day. As you take more photos and study the photos of others that you follow you will train your eye to see! Have fun on the way!
Susie's picture does look much nicer cropped. I noticed her photo last night and thought the same as you, but it was too late to comment then as my eyes were crossing and I was ready for bed.
Oh yes, thanks for the explanation and if anyone gave me such helpful critique I would indeed be pleased.
