Personally, I feel I suffer with the imposter syndrome many times and even though I'm often told how talented I am, I give a courteous "thank you" while underneath I think they are only being nice. The fact of the matter is the complimenters are sincere and the root of my negative thoughts come from my feelings of inferiority when I compare myself with the talents of others; common among artists. The best resolution for this (and anything else for that matter) it to accept my work as others do and continue to improve.
