One challenge is maintaining the pacing. With 7500 words, it's easy to either rush through the plot or drag it out. You need to find the right balance so that the story moves forward at a reasonable speed. For example, if it's a mystery story, you can't reveal all the clues too quickly, but also can't make the reader wait too long.
One challenge CBC might face is coming up with a fresh and original idea. There are so many short stories already, and finding a unique concept can be tough. Another could be limiting the scope. Since it's a short story, CBC has to be concise and not include too many sub - plots or characters that can make the story overcomplicated.
One challenge is the high competition. There are so many short stories out there. Another is finding the right market that suits your story's style and genre.
The challenges are many. One is dealing with the expectations set by the original story. People have certain ideas about the characters and plot of the original, so when you write a new story based on it, you have to either meet or subvert those expectations in a clever way. Also, you need to find a balance between using the existing elements of the original story and creating new ones. In a story based on 'Romeo and Juliet', you could use the star - crossed lovers concept, but then you need to build new sub - plots and develop new characters around it to make it a fresh and engaging story.
One challenge is the cultural differences in language nuances. English has its own set of expressions, and when trying to indianize, it might be difficult to translate Indian concepts accurately. For example, some Indian words don't have a direct English equivalent.
One challenge is to develop the plot fully within a short space. You have to be concise yet make sure all the necessary elements are there. Another is creating well - rounded characters quickly. In a short story, you don't have much room to gradually build a character, so you need to be able to show their key traits right away.
One challenge is getting the facts straight. Since it's based on a true story, any inaccuracies can be called out. Another is respecting the real people involved. You can't just make them do or say things out of character. Also, blending the fictional and real elements smoothly can be difficult.
One challenge is accuracy. You have to research thoroughly to get the facts right. Another is legal issues. You might need permissions from the people involved. Also, you need to make it engaging while staying true to the real events.
