Griffin (B) for me, the wings give it more motion than the ram's horn curl on A. Selling these with full copyright transfer is an interesting model, do most buyers want to tweak the mark before they take it, or does it usually get bought as-is?

The black logo feels like it’s locked in that fierce, never-ending battle .
