There are only two kinds of critics in the world:
Those who don't know what the hell they're taking about, and those that do.
The difference is easy to spot. If you get a critique from someone who's saying that your piece titled "Symmetry" needs to follow the rule-of-thirds, you brush that idiot off.
But what if you get a negative critique from someone whose opinion you respect?
Take it at face value!
Do not take it as a personal attack, and I'll tell you why.
Aside from the people who don't know what the hell they're talking about, nobody critiques a far superior artist. I see artists better than me all the time, and the best critique I can give is, "Wow, man! Your shit is AWESOME!!"
But they also don't critique far inferior artists. It's not worth their time. They don't even click on the thumbnail.
Your critics are usually peers with similar skill sets that actually care
about your work who are seeing one or two things where they can offer advice. You don't have to take that advice. It's okay to disagree with that advice. In fact, it's a point for discussion. You might learn something, or they
Either accept it or dismiss it. Don't get pissed. And be thankful for the feedback.
