Okay, in that case, I'll say sorry for being a douchebag. I'll try not to be a douche anymore
However, with regard to your proof, well, it's just one of many depictions. And that's the beauty of art - you can depict things however you want. As I said in my earlier post, I've almost exclusively seen medusa-as-a-snake-woman (purposefully avoiding the word naga here) on DeviantArt. And, I also did not say that "naga-medusa" is the only correct way to depict medusa - she can be depicted any way the artist desires, and the same goes for races named after her. The depiction on the Forgotten Realms wiki is no less accurate than el-grimlock's, nor is it more. The same things go for nagas - in Hindu mythology, the word naga was used for a lot of things that had to do with snakes - demons in the shape of snakes, human-snake hybrids etc. - in modern mythology, naga is mainly used for half-snake half-human creatures, but the word is also used for snakes with human features, like arms.
I hope I wasn't annoying in this post
Now, to actually comment on this artwork instead of arguing about popculture fantasy creature names...
That's a piece of art. Great work. I actually only noticed the compound-crossbow after brushing past this work 10+ times, and I only noticed her rifle-thingy after clicking the picture. But, as jeroenbrugman said, she might have some problems with the stealth, unless she can, like, tense up her muscles to quiet her rattle or something like that.
Boa noite !
