Feedback - Narrative Art Award

CukiArtist

I decided to challenge myself this year and enter the SCBWI Narrative Art Award.

Here are the instructions:
Submit a narrative sequence based on the theme, “Be careful what you wish for.”
The submission will consist of either three or four images, without text.
Your art style and visual story must be appropriate for one of these two specific audiences/book genres (Choose one):
Full color, intended for a picture book for 4- to 7-year-olds – OR –
Black and white, intended for a middle grade book for 8- to 11-year-olds

I chose to go with the B&W MG book since that's my target audience.
I was wondering if people could give me some feedback including:

Does the story read? Can you tell what is happening?
Is there anything I could do to make them stronger as artworks.
