If you learn drawing or painting or any other skill it is very likely that many more bad than good works arise.
That’s a good thing. Because the bad works tell us where we can improve and show us the next steps.
It can be frustrating if there are deficiencies everywhere. Pick one thing that you want to fix next time and work on it.
It’s best to start with the basics that will help you with each future work. Dexterity, hand-eye coordination, perspective, tonal values, for example.
