If you want some positive comments, you can put it on display at an event,
If you want to try winning a competition that you don't know the judges of, or the prize, you can enter a A&S competition,
If you want to get known for your art, you should teach classes and do active demonstrations if possible,
If you want good useful feedback on how to improve, you should reach out to someone in your field for a direct consult.
And lastly, if you receive comments you don't think are appropriate, then reach out to the runner of the competition to obtain the contact information of the judge(s) to communicate with them further. Maybe they were rushed, maybe they are not good at written communication, and maybe they didn't think about how it could be read as hurtful or inappropriate. Or reach out to someone you trust but see as a mentor to read over the comments in objectivity and possibly interpret them for you.
