Feedback on writing

Hello. For about 6 years I've been a writer who mostly writes for fun, jumping from medium to medium. However, for a long time I've doubted myself regarding if what I'm writing, or rather, how I'm writing my texts is really proper to begin with. I might come off as vague and I get that these things doesn't necessarily have an instruction manual, but I was thinking all I need is a second opinion.

Do any of you all go out of your way to gather criticism on your texts, and if so, how do you go about doing so?
