Anyone willing to try & help me with this?

So, I adopted this story, and now I feel like I won't be able to write it. At least, not as well as the পূর্ববর্তি লেখক did.Should I just write it anyway? অথবা should I tell the পূর্ববর্তি লেখক what my problem is, and see if she can find someone else to write it? Any suggestions are appreciated.
