Ideas for converting a tougher looking vampire on Zombie Dragon

[Bradifer]

Zombie Dragon is already built and painted. 

(Using Terrorgheist head) (Color is green-rotten scheme).

Looking for any ideas for simple model replacements to full conversions - to replace the traditional Vampire Lord that rides on its back.

I wanted to go for something tougher/stronger/scarier, but wasn't sure where to start as I don't have much converting experience.

Skaven Rat Ogres seem lie a neat place to start, but they're potentially too large and furry.

Any of you have suggestions or ideas for a meaner looking vampire rider?

You could try sticking Mannfred from the Mortarch kit on the dragon, maybe with a headswap so it's not obviously Mannfred. I don't own either kit so I don't know how well he'd fit, but from the looks of it I don't think you'd have too many problems. 

Of course this would be especially easy if you've already built Arkhan or Neferata - if not, it might be an excuse to buy a mortarch

I'd look at one of the Stormcast Dracothian Guard Desolators riders, with maybe some Nightlord Space Marine shoulder pads. That'll give you big and bulky with ease

If you'll consider non-GW, try this one and work off some of the more Space-Marine like features

Vampire ogre? They have a lot of models in riding position? 

Or more subtle the old Malus Darkblade on cold one? I could take a picture if you want? Just spray painted it but I dont have a zombie dragen to compare it with (I do have the dark elf black dragon)

But in general, if you are looking of rtough I would look at Chaos knight, Armoured orks, If you are looking at arrogant, slick and more subtle I would look at the elf range. 

Or maybe the Slaanesh lord on deamonic mount with a head swap. that model is brutal.
