I did some chalk drawing backdrops a few months ago for Dr Oz The Good Life Magazine in New York, and I just got a printed copy, yay!
I love this one with the frosty blue colour and wintery trees. Here's a detail of the actual backdrop, where you can see the chalky lines.
And here's a sequence showing my progress as I was drawing.
For the home interior, I started with a more elaborate staircase, but developed my sketches to create a simpler scene. 
I even drew a simplified version of one of my own prints in the background ...
It was a real pleasure to be there on the day of the shoot, here's a little scene of me sketching the set-up.
Let's all walk more this year and get healthy, whatever the background...
