Very nice.
Most of the light box photos I see people post the light is way over exposed and the snake looks like it's in a spotlight. Not much better IMO. But yours is one of the few that definitely look really nice. Good job.
I futzed around with light boxes, but discovered that with a bounced flash off the ceiling, I can get results just a nice and it's way easier than setting up a box. But for people who don't have a DSLR or a flash that can bounce, they should use yours as photos to aspire to.
I agree a zillion percent that people selling snakes need to (try to at least!!!) take better pictures.
