Look at the center of the painting, you would see a Keyhole.

Now look at the purple around the pink, kind of hair with dreads, Togeather you will find a locked face. A Mysterious Woman.
Find the right Key to unlock. Clues in the painting may help you.

Yellow and Black, Relax..Look at the stars togeather.
A pendulam in the white.. Know the swings.
Yellow hands.. She holds the other when she trusts. Similar to the one of baby bird's that mama will be back.

Look closely to the pink in the bottom right...A boot will appear...The Mordenism. From walking the streets of Berlin to dancing the dunes of Burning Man, Her sense of fashion finds expression.
Spot the Rabbit..Randomness
And then there is a Cat with a Hat with a Rat :)
Rings of smokes..Thoughts
Finally, Empty space - An invitation to the other - Open canvas.

If nothing works, Use Magic - Find the Hat, Pull out a rabbit!
