2k pts DE. First list(new to the game) please pick it apart for me.

I just started collecting and this is literally what I have available atm.  
Should I invest in something like 3 more ravagers?
So I guess my idea is to hit really hard with double VR's and Mandrakes and clean up with gunboats, Incubi, Bloodbrides and character support.  This puts me at 7 drops if I got this right?

Yay someone else bothering with Bloodbrides! Drop the Shardnet & Impaler and replace it with more Hydra if you can, it basically sucks since you don't get the +1A.

Are you putting all three characters in one Raider with the Incubi? Might be a bit much. I guarantee your opponent will be shooting there first. I'd personally weigh up whether the 1CP your 3rd HQ brings to this list is worth it - they all have a similar role and Drazhar & the Archon are not as good as Lelith thanks to their borderline useless auras.

If you're finding people are running quite a few vehicles/monsters in this edition as I am, you might find your list is a bit light on dark lances. I'd consider finding the points for a Ravager, perhaps the Reavers/Archon or Drazhar could get the chop.
