I need help with a design

Lillianne

So this is the only picture I have right now. I know it’s not much and I wish I had more.

Anyways, this is the accent wall we have for our nursery. The other walls are the same color as the light grey pictured. I personally wanted a light blue, but my SO wanted this color and I wanted him included with making decisions regarding the nursery so we went with this color. I’m just having a hard time with a theme.

So far I’m thinking clouds/stars and elephants or space like little astronauts or something.

Would yellow be a nice accent color with this? If not then what color would be since it’s a darker blue? Also if you guys have any ideas please feel free to let me know!
