A young girl runs away from her sharecropping life to pursue her dream of becoming a blues legend.

Much like your other logline, this one lacks some fundamental elements - best you check out the 'Formula' tab on the top bar.

This is a situation description, like, a man goes to college, or, mom goes to the neighbor's house. Just a situation. Do a parallel for the Wizard of Oz. This would produce something like, "a girl travels down a yellow brick road." I think you would agree that this would not suffice as a log line for that classic movie? So much more happening, correct?

If it's a biopic, the log line works fine as far as telling what the story is about, but it would benefit from telling?what the stakes or opposition are. ?If she fails to become a blues singer, she can just return to sharecropping and no harm done it seems. ?Who is opposed to her following her dreams which is something most people would support. ?The Johnny Cash and Ray Charles biopics depict a lot of the struggle and this log line doesn't seem to hint toward any kind of struggle.
