Cheers. That's useful. I'm looking forward to getting them, the level of detail and scale looks like a good challenge.
Aptly enough for your size examples I'll be basing them on Warhammer square bases for now, so I can use a 50mm base for the Grand Damned and 25mm bases for Sammael and Foulques. They can always come back off if I pick up the game, speaking of which...
Still open to answers on the other two topics.
