Darling, you don't need feedback to improve, you just need drive.
But first you need to keep drawing until you start seeing your own shortcomings because until you stop being blind to them then no amout of feedback will be good enough to help you.
Like I can tell you that you got problems with foreshortening, perspective, proportions, but if you got 0 knowledge about what any of that even means then of course all of that will sound like bullshit to you.
You got hands and you got eyes, if studying and doing exercises on a book isn't t enough for you then watch videos about shape, construction, values, posing, anatomy, anything that you feel you got troubles with, if that is still not enough then you stare at pictures you like and expand your visual memory as much as you can
Eyeball them then free hand them again and again until you can just retrieve that same image you saw straight from your imagination.
There's not one straight easy route that'll make you not suck quickly that everyone else is trying to hide from you, in the end this shit is all about perseverance, one does not simply improve from simply receiving guidance nor from one piece to another, is simply just doing it again and again and again and building up
confidence in both your muscle memory and your own knowledge.
Drawing is a skill much like playing an instrument, anyone can do it if they apply themselves enough.
And if that's still too much work for you then maybe you should switch hobbies.
