Noice stuff. The Supernatural status seems a bit loaded. Fewer, more pronounced effects would be better, I think. Like, 5% movement speed just seems like clutter right next to 1.5m movement bonus. A mere 5% lifesteal? I'm not sure why Vampires would have maluses to weapon skills. The AP bonuses seem pretty huge.
I'd probably simplify it to:
+30% lifesteal
+Movement (percent or integer, not both)
+Con
Resist Changes
Immunities
I also agree that the issue of slowly starving while shopping and what not could get annoying. The Coffin idea doesn't sound very fun though. I suppose as long as its not too tedious or quick of starvation, it's not so bad.
