I think this is the final version. Unless I notice something that needs changing.
And here it is in black and white.
I designed it as a two-page spread with a bit of room at the top and bottom for cropping if needed. It’s all done in layers, so the signature can be moved or removed and the colors can be individually fiddled with as necessary. The center line falls about where the mom’s elbow is, so nothing important is obscured by the fold.
