This is why people recommend drawing from photos and doing master studies.
You can overlay them when you are done and test for accuracy, as well as comparing line quality and values with master studies of drawings.
The value of copying is that there is a predetermined goal to compare yourself to and train your eye to get better. I think this is the main reason humans have gotten better at art over time, the more art there is the more you can piggyback of other people's work and interpretations of nature and pick and choose what you think works and throw away what doesn't. And of course you can and should look to nature to provide your own interpretations of it, not just looking at photos and art.
If you are drawing your own style and interpretation there is no tangible end goal other than making cool art, there is nothing to judge your progress other than subjective opinions of people who won't truely know your intentions.
If you still have not trained your eye and ability to self critique and set end goals when you start diving into exploring the unknown you won't have any way to really know if you are getting better or worse.
But there is still value to that exploration and creativity that you should go back to between the copying. You have to draw stuff you want to draw and enjoy drawing. You have to mess around and doodle.
So you can go to better artists for advice and feedback but ultimately you need to train your own eye so you can eventually depend on yourself.
