Graphic Design of a high-end nursery construction hoarding

I require assistance designing a hoarding to be displayed in front of a construction site, building a new nursery
There will be 5 panels, cut to the size of 1200 (w) x1780mm (l)

The hoarding company began designing the panels (attached -'panel design v2'), however it doesn't look high-end.
I am looking for someone to help re-design this in a high-end fashion.

I've attached a ChatGPT image of what I'd like the picture to look like (the background colour and font should look like how it's shown if possible. Instead it should be across 5 panels though.
Importantly, the children in the photo should be playing with toys that resemble Montessori (wooden blocks or equivalent, like the picture.
The little leaves and trees featured are also a nice touch if possible.
As the area we are advertising in is quite ethnically diverse, it would be great if the children in the photo reflect this.
I have also attached the 'community play things' picture - I'd like that or similar shown, spanned across 2 panels on the right hand side (ie instead of the picture shown on the right in the panel design one)

The logo can be added once the mock-up design is agreed.
You can remove the built by: (and the Restora logo)

Please let me know if you'd like a video call to explain more thoroughly
