Hello, I Wanted To Tell You That I Came Up With A Story From The House The Dragon X Harry Potter Series

Hello, I wanted to tell you that I came up with a story from the House the Dragon x Harry Potter series and I already created a summary but the issue is that I do not speak or understand English, my language is Spanish and I am writing everything through the translator and I am also not sure about doing the story since most of the stories on Tumblr are without English and I also have very bad spelling so I am not sure about doing it but I wanted to know your opinion or if I should do the story in Spanish Without further ado, I leave you the summary of the story.
