Maybe I'm missing something here, but I don't see a pattern on those ventral scales. One question, does your snake have red eyes or dark ones? If they are dark, I'd go with bloodred until proven otherwise. If they are red, it may still be an amel bloodred, but that would seem unlikely to me unless you paid quite a bit for it. However, sunglows do have ventral patterns unless they are motley, but your snake's dorsal pattern looked normal to me.
