She actually reminds me of the Castlevania's style of Vampires. Specifically Carmilla who has been featured in a number of Castlevania games and recently the Netflix animated series.
Here are some pics of her.

If you look her up on pinterest, there are a lot of images of her, some of which are probably PG in nature that I won't share here since this is a G rated forum.
With her sword, she is like a female Alucard from Castlevania.

It would be helpful to see her mini standing next to the other vampires of Heroscape so that others who are on the fence can make a judgment call.
