I'm doing my leg right now and I'm just going with a bunch of small pieces as filler. Treating the major pieces almost like puzzle pieces. I think it's overall a better visual and the more stuff the better in my opinion.
Really enjoy your work man. I am a huge fan of that style and have quite a few pieces along those lines. Where do you tattoo out of? If it was close to home I'd love to talk to you about possibly getting some work done.
