How to chose background for pixelart?

[bit_aspect]

Hello guys!
I'm a beginner pixel artist and I met a problem with backgrounds.
For example when I draw just one object I choose complementary color as background so viewer could stay focused on the object.

When I try to draw a landscape I draw all the background I need.


But I'm a fan of small scenes like flies near the lantern, or leaves of sakura flowers falling off the trees, or little buddha statue under rain... so when I use solid background the whole piece looks really empty. But when I begin to add background objects, the whole scene gets lost in details. So I can't find balance between this two things.
I can't make blurry background because of pixel art restrictions, but I want my art to be complete. Looking for your advices and sry for bad english.

Try to look at what other people do, and perhaps play with saturation stuff. For example, on the mountains I'd try some squared clouds to match the geometry stylism. And for the bush it'd be subtle shades of brown to imply trees and dirt. Etc etc.
