Digital painting yellow lights

Before, when it was plain ball point pen drawing, you couldn't tell what kind of light or color it had. That's been solved now. I drew this drawing in the first place because of the amazing lighting of the photograph.

And I tried too capture as much as I could of it through the digital process.
I am quite happy with the results...

let me know your thoughts in the comments below.

Here are some process shots of this of drawing:
