Demanding sense is reasonably tricky to comprehend. It refers to someone who is exceptionally choosy and nitpicking. A persnickety individual usually pay strict attention to detail and has high standards when it comes to criteria and excellence. Their attention to detail can be seen as admirable, but it can also intensify unreasonable disapproval and unjustified dissatisfaction. Being persnickety is commonly associated with detailed focus on specifics but can also be seen as a manifestation of pedantry.
