like everyone said before already, let me say it one more time to make it clear.
this is a tutorial, therefore 0/10.
tutorials are done so that you will learn from it, so whenever you do a tutorial don't follow it completely. give your own twist to it and think beyond the tutorial, "HOW CAN I USE THESE METHODS IN ANOTHER WAY?"
doing graphics is all about being creative so don't ruin that sh1t, it's bad for your health.
