Anyone with a mountain accent wall in nursery?? If so, please post some photos in comments for inspiration!

My son is almost 18 months but we moved so I get another chance to decorate! His nursery as a baby was wood and metal industrial vibes but this time I want to give it more of a big boy feel and painting some mountains. I’d love some visuals of what everyone else is doing!

OR if you have a cool unique theme please share! I’m still open to ideas since we haven’t completely started.
