hard to tell. thats a bit of a problem with that gene complex, the normal forms look so normal, while the combinations and super-forms are stunning and awesome.

i would say the sure way to tell it would be to breed to a mojave or super mojave BEL (or any other BEL). By the way, today in another thread a discussion is leaning towards the conclusion that phantom and mystic are two different names for the same gene.

from only the picture, i think its likely there is something like phantom or mystic going on in that snake, but i dont think its mojave. im not sure, but i lean towards the hypothesis that you got what you wanted, and that your snake will do something nice in the blue eye leucystic gene complex.
