Oh, you're a talented sculptor!
Would the figures fit & rank up on 20mm or 25mm square bases, or are they better on 40mm bases?
I'm trying to figure out if I have a need & role for these in my armies. 
Due to an unfortunate lack of talent I did not sculpt these.
I had not seen a thread about them and thought others may like them as much as I do. Shame the KS is not better publicised as it is struggling a bit.
According to the background on the campaign page the figures are designed to provide figures for a "Scarecrow" unit in the Night Stalkers army for Mantic's Kings of War game.
KOW uses 20mm square bases so these will need to be compatible with that, given the poses I would probably arrange 4 on a 40mm base rather than try and rank up individuals on 20mm.
I want these for skirmish games so will be using 25mm round bases. I have a few Westwind and Chronicle ones already and use them as summoned creatures with Skeleton stats or as Golems. Loads of possibilities for these guys.
