What a great room!

I am leaning towards the Orange bedding.

I would lean more to the green or blue as they may lend more to relaxing in this already colorful room

I was definitely blessed by the fact that my son has always been easy to get to sleep and has always been a great sleeper. He has never struggled with getting to sleep and staying asleep so I'm not really worried about the relaxing part I just want what looks best and is most fun and enjoyable for him! Thanks for your thoughtfulness though!

It looks like you’ve narrowed it down to the orange and the green. Why not let your son choose which one he likes best? It will give him a sense of ownership and control that kids love.

IMO ask him I have always found kids have favorite colors and they also change those every year or so . I tend to not paint the walls the favorite colr but keep the walls pretty neutral and change the bedding and accessories to the color of the year unless of course you love painting.I love the wall paper and IMO let it be the star and do the orange bedding I love that wall mural

Orange

I'm a sucker for avocado green, so that would be my choice. But the orange works great with the mural too. The aqua goes color-wise but seems boring compared to the other two.

Orange for me.
