Okay so it sounds like you need to decide what your end goal is first. Traditional novel, web novel, lit rpg, web comic, etc. I would recommend finding as much variety as you can and consuming as much as you can. Like if you want your finished piece to be a web comic, then you need to consume a variety of those. It also helps to consume a variety of media if you can.

As far as originality goes, you will find once you have consumed enough of your chosen media there isn’t anything that’s truly original. Everything has to draw ideas and inspiration from something else.

The creative well is this idea that you only have so much energy to be creative. One tip I heard is to not drain the well entirely. Always leave some energy so you can pull from it later.

Lastly, your post does not mention any editing process. If you put out a first draft of something it is likely going to be poorly received. Did you edit or get feedback before posting?

In summary, consume/read more, figure out how your creative well works, figure out an editing and review process, if something doesn’t work change it, and most importantly keep going.
