I like yellow but that is a lot of yellow.
And you have 5 weeks to get it finished? Yikes!
I would go simple: snowball 9patch.
Here's the pattern:

And here is a coloring book page so you can try out different colorations.

I would probably make yellow "balls" with green corners and 5 green squares in the 9patch with pink background. Hmmmm... that might look like flowers with green leaves.
Have fun with it. But hurry!
