Original ideas aren't too scarce.. but it's okay to get inspired by people of course. Literally one of the levels on the works for my hack is called Koumei's Forest hehe
There's no way to be completely original most of the time, although there are many ideas you can take advantage of that you could test over and over. It's alright to gather inspiration from other people's work and even expand them until they get beaten to the ground, as long as you don't flat out steal their material.
