I would be glad.

The unholy darkness mod looks good, it isn't out yet though. It's on the same page as this one

The Vampire experience mod looks good as well, http://www.gamesas.com/bgsforums/index.php?showtopic=1078548

Indeed Unholy Darkness looks nice. Personally, I've been holding off making a vampire until that's out....and that time is upon us soon I believe!

As for something that's out, everybody always praises this one for being awesome (it IS in the name anyways)

It seems good, but it didn't quite fit what I wanted so I didn't use it myself. Not saying it's bad, but I didn't like it.

The second mod seems good, I wish to know others with lots of features like Nekhanimals vampire mod.

There are some other's too.

http://www.tesnexus.com/downloads/file.php?id=27329 is by far the most endorsed at Nexus, although it loosley based on http://www.tesnexus.com/downloads/file.php?id=2243

http://www.tesnexus.com/downloads/file.php?id=16417 is very popular too (and there's a OOO/FCAM patch out there too, if you need it)

I'm planning to become a vampire (and haven't done so vanilla wise) so am spoilt for choice.
