jo3, thanks for reviving the thread.
your photos - look like ordinary snapshots
they're photos anyone can take - anyone with any camera can take
I suggest you try adding a personal touch to the composition
Something not expected not already familiar.
Something I learned though sadly not always practiced is as follows:
when there's a bunch of you photographing the same subject try to
capture the subject in an original manner, not the same already
familiar pose. go for a tight crop or a different perspective.
make sure when all the photos of that same subject is put on a wall
your depiction is different from the rest and stand out.
Of course, basic rules of photography should have already been
applied to the composition before you add your signature. A deviation
from the basic rules sometime make spectacular photos, as well, but
few can get away with this.
