Thumbnail Feedback Our first attempt at a DIY video | Kids

[TheHappyKidShow]

Hope all is well! Looking for feedback on this thumbnail for an upcoming video. It's a DIY on building a kid's toolbox.
I don't ever put text on my thumbnails as this is a kids channel, what I would like to know is if the colors and imagery alone feels strong enough for a parent or child to what to show or watch with their kids... See below... Thanks!

I got a question, why is the background pink?

You know we saw a lot of kids channels had a colorful packground, and this was the color my kid liked. So just tried to stick out more.

Try to experiment other colors too, to see which one will stand out for the audience.
