not very good lol

Comes with practice my friend.

Keep on doing tutorials, It will show you some good techniques and things you can do to better your signature. In no time you will have a good knowledge of what works and what doesn't.

It's the best way to learn.

Experiment.

Did you use paint or summin?

Do tutorials. By day 5 you will combine all the techniques you learn and make something really neat.

Good Luck on your journey and do not give up like I did.
