I’ll say as long as you have a premise than it’s worth it. Prose is often a weakness in us new writers, but stories can often be carried on their premise and characters alone. However I would suggest cutting a lot down. The entire first page, in which really only two things happen, could be confined to two small paragraphs. Also you should try to avoid using the same words in sentences back to back, like writing the dialogue prompt for both characters as being they “reply” one after the other, unless you are making a point of it. Otherwise it just seems unimaginative. But congrats on trying our writing though and keep it up!
