It does not devolve into a queston of personal taste. It revolves around what is called the “reasonable person” or the “reasonable expections” test. If the fauxtog held themselves out to be a professional photographer, what would the reasonable person have expected? That is the test that would be used. But again, since we have no idea what the (apparently) oral agreement was, what was said, what was or was not proffered as samples or examples of work, no one here can say whether or not the fauxtog met the requirements of the agreement.
Has the fauxtog contacted the OP about payment? I’d be curious to know. If not, why not?
