But It Was Such a Nice Rejection Letter

I got a rejection letter today on my October Bell story. I had sent it about two months ago to JourneyForth and was expecting to hear something soon. I must say that I'm not surprised. I did think the story too mature for the type of book that it would be targeting (picture book). It was just a story that needed to be told. The letter said that the acquisitions editor saw the book "as a picture book for an older audience" with "vocabulary" and "concepts" that are "much older and wiser than many would find feasible for a child." She also says that "it is a nice story with the flavor of Sarah, Plain and Tall" but regrets that "as it stands, it is not a good fit" for their publishing house. She does mention that she would give it another read were I to attempt some revision. So the choice before me is to rework for that same house or send it along to someone else. I'm sort of torn between the safety of a publisher I've had past success with and someone new. I will definitely use some of the editor's suggestions before I do anything. Then I will take a look at my chart and see what's next in line!
