What is your favorite background ? (Patreon)

I'm currently working on a piece, What kind of background do you enjoy ?

On my side, I love minimalistic background, creating original and unique piece focused on the bodies, the actions... something like photos more comming out from a studio.

But what is you point of view on that ?

Option 1 : I enjoy unicolor background, focusing on the action, the light and the characters, background are unicolors (full white, full black, full one color) like the picture above I'm working on :

Option 2 : I enjoy a simple background, we can see walls, ground, but as the same as before, the attention is more carried on the characters, like I did with "Toys' Mayhem", my graphic novel

Option 3 : I enjoy a more complex background, more regular renders with visible rooms, furniture, etc... even if blurred by the objective blur 

Give me your thoughts, don't hesitate to elaborate in commentary section 💜
