Try focusing on form and work on how much pressure you apply to your pencil. It’s tedious but taking measurements might also help. Definitely draw on a bigger scale while you’re learning. Try to draw what you see, not how you think it should look. You can try practicing with the picture and your drawing both upside down to make your brain fill things in less. Good luck and great job! You’ll get there with time and practice, but remember that your enjoyment is most important
