Particular sense is fairly elusive. It refers to someone who is exceedingly choosy and critical. A persnickety individual tends to pay strict attention to detail and does not settle for less when it comes to criteria and flawlessness. Their fastidious nature can be viewed as laudable, but it can also magnify unreasonable censure and unnecessary dissatisfaction. Being persnickety is commonly linked to thorough attention to detail but can also be seen as a type of perfectionism.
