I feel like this often, I wonder if I'm bothering people by uploading sketches and unfinished work, and in my past experiences, it bothers people to see unfinished work shared. It's seen as lazy and wasteful to post. However I typically disagree, I find sketches and rough works MORE beautiful.
But yes, it's probably something I could stand to learn, how to focus on my wants as an artist and not everyone else' opinions restricting it so much.
