Just finished up my own rendition of Elianna's (http://www.furaffinity.net/view/13717775/) naga form. I initially started with a base sketch provided by  ryagon, but my artistic side kicked into high gear and i ended up using only a small portion of the sketch.

Elianna is a Titanoboa Naga and, as such, is an incredibly large individual.
