Today I bring you a concept lora based on the naga from the Warcraft series of games, specifically female ones because the only models I could find for Warcraft naga were exclusively for the males, and I don't roll that way. To reiterate, I will NOT be making a model for the males, so don't ask. Anyway, you should be able to do them pretty nicely with this, and probably even turn other characters into nagas if you so fit.
Trigger word: wnaga
Appearance: monster girl, mermaid, lamia, scales, head fins, colored skin
Optional: extra arms
Recommended weight should be somewhere in between 0.8 and 1, but you should experiment to see what works.
