You didn't fail - you found 20 ways to improve it ;)

Some advice I can give you when it comes to drawing:

1. Some think drawing is a gift and we are born with it. The fact is that everyone can learn to draw well. It's all about practice practice and then more practice

2. Be patient. Don't feel frustrated. Enjoy the process and don't focus too much on the end result.

3. There are some basic very important techniques when drawing. Study on YouTube. YouTube is your friend.

That's pretty much It :)
