Most artists draw upon their own experiences and feelings to find inspiration for their art. Try creating a love story that is based upon your own romantic experiences or a fantastical story that brings your most serious or silliest hopes to life. You can also manga-fy a friend’s eventful life.
Another great way to come up with storylines and characters is to look around you for inspiration. Ordinary people that you see and come into contact with daily can spur intriguing characters. Take time to simply observe people and imagine what their stories are.
