Honest review from someone who once drew a drawing exactly like that:
Your rating is 1 out of 10, your level is absolute beginner. (the lowest possible level, someone who lacks practice, knowleadge and tecnique)
Good news is that your improving potential is all there, you just need to practice and learn the basics.
You might not be aware of that right now, in your mind your drawings are awesome and people are just being mean to you, but believe me, one day you'll look back at that drawing and realize it
Drawing is a very demanding task, both mentally and physically, only time will say if it's your thing or not.
Good luck.
