Edit: Nevermind, I finally found it.
Some 15 years or so ago I had a very nice very large piece of of artwork by Masamune done on my entire shoulder / upper arm when I started my full sleeve tattoos.
I would like to get it touched up by my current artist but I am having a problem finding it via Google.
It is basically a cyber-punk like cat girl holding a giant koi fish over her head.
Here is an example of some of the same artwork around that era:
I think it may have been from a magazine or calendar at the time.
