So, aside from you borrowing Scorn's system (really, look into that, it's a perfect compliment to yours), here are a few other ideas:
1. Separated Night Eye and Life Detection. Yes, vamp senses are cool, but they don't always work together--sometimes I need to detect my prey in well-lit areas. You could call the Night Eye effect "Vampiric Sight" and the Detect Life "Vampiric Smell."
2. I totally jacked this one from http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=771, a Morrowind classic. Instead of straight hypnosis (the "look into my eyes" thing), you could do a "victims and thralls" system. For instance, you COULD beat the NPC to the ground and force him/her to follow you, or you could seduce them over a period of days into becoming your willing minion, and eventually a vampire themselves.
3. A proofreader. No offense, but your grammar is a bit... erm... lacking. If you like, I'll be completely willing to do this for you. In fact, if you need anything written, I can oblige--a readme, that vampire skills book, whatever. Just let me know by posting in this thread, it'll send me an e-mail. ^.^
4. Getting rid of auto-sun damage, or at least having an option to toggle it (as a cheat or for RP value, etc). It's annoying as HELL to have it on all the time.
...and that's all I can think of right now. I'm sure I'll think of some other stuff later. *rushes off to go play your mod*
