Inspiration - Backgrounds

I have found some animations on you tube that have some cool background styles that I could incorporate into my animation.

I really like the background of the outside of the house in this goldilocks animation. Since my setting is outside I could create something like it for my animation.

I really like the simple background in the first part on the animation and I like how it uses different shades of one colour. This could be a style of background I use in my animation.

I also really like the style of background in this animation but it could be a little hard for me to do.
