That looks like the crosses I used to make in the early 90's using the only Martir I had at the time crossed with Juarez stuff. I stop doing those mixes in 94 and wish I had not done it all. No need to for me to cross now as I have several pure Martir stock. I wonder if that snake in your pic is one of the outcomes. Looks nothing like a pure Martir. That's a classic Juarez head pattern and triad style. Has some of the Martir pinkish hue though and only a handfull have that. Nice snake though.
