Pink ~ gradient pink series, flowers with overlapping shades ~ romantic flowers falling in dreams ~ are highly recommended, which is very suitable for the fashion and romantic theme of your room.

Hand-painted TV walls are very popular now, especially in the shape of flowers, which are full of warmth.

There are many such pictures on the internet, which are helpful for your search ~ Baidu picture "painting?" The background wall is much better.

This is my favorite, and I think it suits your family's color scheme.
