So... I'm not sure if I can fairly call myself a writer. All of my work is roleplay, specifically I run a very story oriented D&D game where the rules of the system are simply there to allow for more natural and consistent story telling despite there being 6-7 players. I am considering writing very short stories in order for me to play with all the character concepts I come up with in my head. I study tropes and literary devices quite a bit, so that I can try and be critical of the material I put out for my players, but sometimes I feel like just doing that isn't enough to get me better at writing and by extension characterizing my ideas. Soooo yeah.
Hello. The more you write the better you get at it. But feedback helps. Sounds like you have continuity problems, and should reread your work regularly to keep the cannon of each story straight. Though I could be wrong. Good luck and have fun.
