(Arc?)It is fun! But sometimes difficult. I struggle with making each character unique and giving each a good character arc and backstory. In my story there is a main character, a couple super close friends, and six or seven others who are important. Any tips?
You have a great system there! I do fanfiction, so I have characters to research and personalities that are already set. As for coming up with your own, I have two or three personal characters.
For making one main character, try taking your own personality and appearance, and change it around a bit. Or, if you have a favorite character, base them somewhat off of that.
I hope this helps some!
