Second Story Rejected with Request for More Stories

My second story for this project, a story set in Norway post-war, has been rejected. The rejection came with an invitation to submit more work. My readers know I am now behind schedule on story writing, but I will shortly catch up. Here's the rejection:

Dear Anniken,

Thank you for your submission "Hjemmelandet". We regret to inform you it is not what we are looking for at the moment. It came across as too dense and it read more like a novel outline rather than a complete short story.

What we really like is your writing style. We would be more than happy to read something else written by you.
