I like to repeat this mantra to my fellow artists out there:
The opposite of perfection is DONE
But that's a lot of what everyone else has said so far, so I'll give you another take that may help you.
The two components to "improving" is understanding where your current taste is and where your current skill is. Current skill is obvious, its how well you produce the stuff you make. Taste is basically what you can objectively "see" in your own stuff, in others, etc. For example, if you see the Mona Lisa, your taste will notice the style, the technique, objective qualities. Taste is your baseline for "What's Good" which is subjective of course, but tldr its that.
A lot of artists get stuck in that art block because as their taste grows, the skill starts to fall behind because being able to find observations and make those big brain connections is usually quicker than the ability to physically learn the techniques and understand how to execute them well/consistently. What they SEE as "good" develops faster than their ability to create "whats good"
SO TLDR; take a step back and look at what others are doing. What do you like about it? What DON'T you like about it? What are some elements about THEM that makes their story effective TO YOU? And then flip the script on yourself. What's still working for you? What isn't? Comparison is a very slippery slope, but if you tread carefully with an objective eye and patience, it will really go a long way as you grow as an artist
