Welcome to the Inkwell, @officialvictor. You begin your participation in this community with a well-developed story. You have a strong narrative arc and strong character development. 'Boo' as an indication of disapproval: great idea.
Your protagonist experiences more than one conflict. She must go on stage and perform. She must handle her relationship with Raymond. And, she must deal with her grandfather's illness. In each case, your resolution is sensible.
Thank you for sharing this story with us. We are happy to greet you warmly as a new writer in the community. Please review our rules to ensure that your experience here is trouble free.
