Particular importance is fairly difficult to understand. It refers to someone who is extremely picky and critical. A persnickety individual tends to pay strict attention to detail and does not settle for less when it comes to criteria and perfection. Their attention to detail can be regarded as praiseworthy, but it can also intensify overly demanding disapproval and unjustified dissatisfaction. Being persnickety is often related to precise attention to detail but can also be seen as a form of obsessiveness.
