The Queen of Hearts
I’ll start painting the Queen of Hearts, the character that’s furthest in the background.
I add more contrast than the background, while keeping a sense of distance.
This character is the furthest of all the characters, so I keep that in mind while painting the details.
 Card Soldiers
I’ll start painting the cards. At this point I belatedly realize that the pattern for each of the cards needs to be different...
I carefully paint the cards one by one. I imagine that the cards on the bottom side are not yet transformed into soldiers.
I also paint the border on all the cards.
I paint the patterns all the way to the cards at the bottom. Keeping in mind the perspective, I add more yellow-green tones from the background as the cards get further away.
The layers look like this.
To help the cards blend better with the background, I add a new layer and paint lightly in yellow.
The card soldiers look like this when I’m done.
So far, the whole piece looks like this.
