The word "more uncomplying" can be a little difficult to find antonyms for, since it is a comparative form of an adjective that already has a negative connotation. However, some possible antonyms could include "cooperative", "obedient", "compliant", "yielding", "acquiescent", or "docile". These words all suggest a willingness to follow instructions or conform to rules, which is the opposite of being uncomplying. In general, antonyms for negative adjectives often describe positive qualities or behaviors that are related to the same concept, but in a more constructive way.
