Tip # 3
Learn from different graphic artists. Check this video from Mary Doodles.
Another graphic artist I admire is Joanne Fink .
Check her tutorials.
Her patterns are a great way to practice penmanship and you can try with both a regular pencil and a digital one.

Also, check Pic Candle youTube channels for cute doodles
here is a sample of her work:
"Doodles by Sarah" I must watch .... quick small doodles done inside a circle...pretty cute, fast & easy...good practice!
