Writer's Fallout Shelter

Hey there, I'm welltoasted, a newbie to this site's community. While I took a 4-month creative writing class two years ago and have read a good deal, I don't remember the basic elements of writing a story, at least not entirely. I know about including conflict, choices, climax, denouement, dada dada... but I wanted to hear from people like you who are actively writing, rating, and reviewing, or at least have some sort of fiction-authoring experience.
I have plenty of ideas and all that, but I'm basically trying to mesh it all together, and I don't want to continue my plans going about putting it together the wrong way.
Any and all feedback greatly appreciated!
BTW, I apologize if this's "OT"- given the nature of the intro I figured this would be alright?
