Here's a gif showing how I made these recent art pieces.
I start by drawing the foreground
Then I focus the colors, saturation and lighting based on where it is.
I make sure the transition isn't obvious by adding props on the background.
These props are improvised meaning I just made up a story in my head based on the foreground (which I just sketch while I'm bored)
And with all those props it ends up creating a background providing some sort of story element.
TL;DR
I draw something randomly, making up a story about it as I draw the background
Which ends up having a detail art piece that has a story behind it.
