I uploaded something, wow.
Who else is a big fan of Zangoose and Seviper pairing? About 1-2 years ago i came up with a story of such pair. It's protagonists are Razorclaw the Zangoose and Seth the Seviper.
And yes, both of them are males. M/M pair. I have plans to make a comic out of this and i have managed to do some work on it. No promises when exactly it happens, but hopefully at least during next year. I currently have their visual references in-progress so that's something.
I'm not too familiar with the anatomy of snakes, but i'm getting the hang of it.
