User blog:TDKMC1/My writing style

I'm on here mainly to improve my writing skills. I feel that I'm writing mediocre stories and want to improve on them. I've never been one for writing gore- I prefer pieces that leave the reader anxious and uneasy. I like the subtle touch. I'm writing this post to solicit ideas from the other contributors. Here's my questions:

How does one create a good buildup in creepypasta? I don't want my stories to start with "ho-hum, just another day in Bumfuckville." However, starting them smack-dab in the thick of it doesn't feel right, either.

What about an effective denouement/ending after the scare?

Is it more effective to write on supernatural horrors or everyday ones?

Please respond! I need more food for thought.
