Tinkering around with a new revision strategy

I wrote a picture book story of Black Creole girl a while ago. The few editors that responded did like it, but they either a) weren’t in love with it enough to buy it OR b) wanted me to up the stakes.
One particular editor commented that as she read it, it made her want to get up and dance. This is actually my favorite piece of criticism so far. It stuck with me.
Last week, I decided to dust off the manuscript and try it again. I printed it out and took notes directly on it. I made a list of things that I wanted the new manuscript to do. I went through with my trusty pen and crossed out everything that I didn’t think would help  to reach my list of manuscript goals.
I have about four sentences left, and they’re still not fully exempt from the chopping block. I even changed the title! Was it hard to get rid of that much text? I’ll admit that I did pout for like two minutes. I got over it though.
I feel fortunate that I”m not one of those people who gets extremely attached to their writing. Did I love this manuscript enough to revisit it? Yes. I guess that does show some attachment. However, I’m not so attached to it that I’ll horde words just for the sake of keeping them, especially if they’re not beneficial.
I’m sorry! I haven’t touched upon the title of this post yet. I mentioned that the editor mentioned liking the sound of the manuscript. So, that’s one area of focus I’m really trying to bulk up. Remember the cartoon Madeline? I loved how it sounded as a kid, so I’ve started listening to old YouTube episodes of it as I do my revisions.
Will this land me an agent or result in a sale? I have no idea, but I”m having fun. Never stop having fun on your writing journey.
