Doing away with negativity

Hi everyone I'm just letting everyone know that I'm not taking any negativity from people anymore. I have had someone tell me to put fuller harmonies in my songs. Look I appreciate input but I feel I have created "my sound" and people are liking it. So when I respond and say this and state doing too much would make the song too busy and the person replies: they already are. To me that is being negative and picky. This person has been blocked from my Facebook and artist page. Hope everyone understands what I'm saying. Thank you
