Unless you know for a fact that your snake is carying a motley gene, I would call that one a homozygous stripe that is also cubed. And your name of "striped cube" would fit perfectly. Some homo stripes are not perfect and have some connections between the stripes. And I'm sure not all cubes are completely cubed, having some striping as well. By judging by the distance between the stripes and the thickness of the stripes, if that snake had a motley gene in it, I would be very surprised. But a test breeding would tell you for sure. Awesome snake in any case! And I wouldn't be concerned about the slight peppering of the belly as it gets closer to the tail. It happens quite often in motleys and stripes. I have a motley ghost female that has a solid white belly towards her head, but it quickly becomes an almost solid grey color (that basically matches her saddle color) as it moved towards her tail.
