My First Agent...Maybe?

So I've had this children's mystery story that I wrote a few months ago just sitting here--all unedited and lonely. I decided it needed a new home. I did some final editing, Googled a children's literary agent, and submitted a synopsis. Hopefully, I'll hear back in a few days. Even if it's my first rejection, I hope I get some positive feedback that I can use to improve and not just a form letter. We'll see!
