"More welcoming" could be considered as an antonym for the phrase "more unwelcoming". Other possible antonyms might include "friendly", "inviting", "warm", or "approachable". These words all convey a sense of openness and hospitality, unlike the negative connotations associated with being unwelcoming. It's important to note that the degree to which a place or person is welcoming or unwelcoming can vary greatly depending on context, culture, and personal preferences. However, striving to create a more welcoming environment is often a key goal for businesses, public spaces, and social interactions in general.
