I use to get extremely harsh criticism, I realize I have a color blindness between subtle reds and greens. So people unintentionally would criticize my use of it. I didn't think it'd be just me until 3-4 years ago.
When I was a teenager, my art would be placed on a Snark website, where people would often point, laugh and make fun of my work at the time due to how my anatomy was since I was still trying to teach myself on how to draw bodies properly. My characters were colored drastically and I'd often use bold colors because it makes it easier for me to differentiate between characters n such. My writing wasn't /bad/ per say, but it was definitely something a teenager would do. But more often than not back then I was told, "Your art will never go anywhere, you suck, why are you so bad at XYZ", recently the harsh criticism I've gained is "Why are you so bad at backgrounds" in the middle of a call of my own comic discord, and it was someone legitimately shaming me out of anger and what felt like jealousy.
