I impressed with your confidence in your characters and in your writing skill. That’s refreshing.
To me, they seem wire-frame like without bodies, weight, height, appearance, real characters and some kind of a correlation with the real life. I understand your premise and what motivated you to write the story. What I don’t see if how your protagonist went through this extremely stressful situation being broke, dumped and turned out to be a winner. If I was to write such a story I’d concentrate on those moments, which are the most interesting and which you didn’t bother to flesh out as self-evident. It is one thing to be an aspired writer and a totally different to actually do it and succeed in this field in a real life.
However, who cares what I think and feel as a reader? Most importantly is what’s going on in the writer’s mind. That is the real treasure.
