@chrisaakins I think you were very successful, but yes that is tedious. Maybe I'm missing something, you said you multiplied the layer so that should eliminate all the white. You should be able to have a layer underneath that for the dragon, and another under that for the background:

Alternatively, if you want to get rid of the white completely you can open the layer styles and move the right slider on the "This Layer" until you like the way the linework looks. I don't find this method to be very precise and sometimes you need to clean up the work a bit:
