Complete digital painting in photoshop, all in one layer

Hello everyone, i finished the digital painting. This is another one of my one layer painting. I have to say that painting in one layer is much more fun that doing the regular way.
It feels a lot loose and easy and freeing. I really enjoyed every bit of the time of drawing this.
I really like the strong yellow light on the side of her face.

Here are some process shots:
