Bringing Ghostbuster's to Life (part 2)

Here is the second step in my creating a Ghostbuster's inspired print/poster.

I've taken the base pencil illustrations (did in part one) scanned it into my PC and refined it in photshop.  Here, I'll add to the contrast, deepen the blacks and add highlights.

Now the image is ready for the next step...

Next: Designing the finished look of the print.
