My First Short Story: “Dreams”

I’ve been writing stage plays for about 30 years and screenplays for about three and recently decided I wanted to learn how to write short stories as a new challenge. I’m working my way through an online course that’s based in London. A couple of weeks ago I completed my first story, about 5 pages. I received feedback from the folks in London and this is what they wrote: A delightful story that really brought your characters to life. Brilliant work!
Brilliant? Where do I go from here? Maybe I should stop now. LOL
