This topic is not really suitable for new artists.
I think I should point out a few things.
As a beginner, quality is more important.
You need to learn how to practice first before you can draw fast. Learn how to walk properly before you can run.
As a student, both is important at the same time. Now you learn how to deal with deadline.
You need to learn how to balance your art quality and finalize your project for a fixed period of time.
As a professional artist, speed is more important.
No matter how fast you draw at this point, your quality is always at the acceptable level.
The diffirent between a professional and a beginner is at the art quality, because anyone can draw fast.
