So, the photo is about repetition. That is your thesis.
So, now eliminate things that don't support that thesis.
Well, the wall at the end says "Ok, the arches stop here" - that hurts your thesis. So get rid of it.
We all polish a lot of turds as we dive into photography. Hopefully some of these ideas can help future excursions.
