I've finally managed to get an agent interested in my picture books (wehey!). She emailed yesterday and turned me down, but has said that she'll happily see them again if I 'revisit' them or write anything else. She gave me a little bit of feedback, just to 'loosen' up a little and remember pacing. I've had a look at what I sent to her and used her feedback but I can't be sure that I've done what she's asked for as it's so vague.
Should I send the new version to her, along with a new text and risk her saying no again?
