Welp AndreaVonReding it took me a couple of months, but here it is! I took a few liberties with your request since you mentioned mountains and an ice tower and my mind just kinda took over lol. Sorry! Please let me know if/when you decide to use it and don't forget to credit me in the description of your story if you do! :)

Also, I drew and painted the snake, mountains, sky, and tower by hand. Only the ice textures, and the snake's eye gem isn't painted by moi. So yeah lol.
