Those look pretty nice. How does Warlord's resin compare to other companies to work with?
The resins are actually from Prodos which, no matter what you think of them, are some of the best in the business. They have enough 'bend' so that they aren't brittle and snap like some resin miniatures which allows you to get some very fine pieces that aren't a break hazard (the legs on the mortar and lead for the dog for instance). Also if you do have a piece that is a little out of shape the old hot water/cold water trick works a treat (and is great for customising as well).
How did you do the bases ?
I use Vallejo's 'Black Lava' which is then painted 50/50 black and cold grey, highlighted with a dry brush of cold grey and then heavily washed brown.
