Need to work on scale

I really need to work on my scale.....make one thing the wrong size and it throws everything off. See if you can figure out what I mean in this mural.
She did decide the right side needed something after all.
This one is done, today I clean. This weekend I'll be doing another nursery, this one with animals. Here's a sketch for one of the walls.
I'm starting to get interest from artists who would like to display/sell their work at My Studio :-)
