Yep, a better drawing would have helped.
I think if ya want to use that pic, you've got to stop adding your own lines.
If you invert the pic, tool in the black areas ONLY
when you dye it, the high areas will be black and the tooled in would be silver/white.
Seeing what you've done so far, you should be able to pull this off
Well, that's my 0.02€ worth.
