I tend to spend more time on my backgrounds (including settings) than I do on the main subject of the drawing:
Like this early Wild Nights, Hot and Crazy Days image. The background is a mid 1980's K-Mart:

And this WNHCD image as well. Believe it or not I was proud of those rocks when I drew this (I had not yet learned how to draw using layers, this was done "flat"

As I've improved and learned the tools of the software I use, the backgrounds got better. I love doing mountains, and this one from Defining Daecon is one of my favourites. I love the bear, but I really love the background. Discovering how to use layers really helped to give this one some depth:

More mountains

And that little bitty cabin you can see there on the lake shore? Here's what it looks like inside:

Yes, I like doing building interiors too (this one is modeled after the kitchen in a 150 year old farm house my husband and I renovated back in 2006):

And a modern, contemporary living room. I like doing interiors because it lets me experiment with textures (much of which gets lost when the image is reduced to Tapas size):

Sometimes the background can be people, too (though I did go overboard on the detail of the Great Hall interior here as well - more fun textures!):

Speaking of textures, I love the way the water and coral turned out in this old MerMay drawing (but I am disappointed because the Tapas shrinkage robbed Daecon's scales of their pearlescence)

Alien worlds can be fun too. Here is a fanart of @MK_Wizard's Psychoborg (I'm not even gonna tell you how much fun I had with that motorcycle):
And another fanart, this one my Daecon meeting @skidiggy's Zayzann:

And an example of how much detail is lost when an image is resized for tapas: That "Moon" in the image above is actually a planet, and that planet has its own moons:
