criticizer
One who nitpicks
A criticizer is someone who criticizes—who finds fault or expresses disapproval.
The word carries a slightly negative connotation, suggesting someone prone to criticism rather than someone offering thoughtful evaluation: He's such a criticizer—nothing is ever good enough for him.
Critic is the more neutral term for someone who evaluates.
