Need help with transfer essay!

Hello! I’m trying to transfer into the fall semester at other schools. The deadline is coming up, and I’m feeling a bit nervous about my essays. One of my schools I’m applying to has this prompt :Please provide a brief statement that addresses your reasons for transferring and specifically why you wish to transfer to (school name). 250-500 words preferred.

In my essay, I was told to mainly focus on why I find the school a good fit, but now I’m worried that I only focused on the good aspects of the school rather than the why I want to transfer. I didn’t want to complain about why I want to leave my old school. Is there any advice on how to write an essay like this? If someone’s willing to read over mind, I can also send it as well to them through a PM. Thanks so much.
