Thanks for the kind comments all, they're much appreciated!
I'll see what I can do about those close-up photos.
deathjester25: Slightly smaller assassin is from Citadel's AD&D range with some minor conversions (added some pouches to his back). The other is a conversion with parts from Vendel, West wind and Citadel.
thebinmann: That's an old Citadel ogre standard bearer with some greenstuff and mallet made of cross dowel (which I found under the sofa).
Franz_Josef: Freelancer was converted using body from Gamezone halberdier, head of Citadel's 6th edition empire champion and right arm of some mordheim figure (marienburger youngblood?).
Sirolf: According to stunties.com (
http://stunties.com/wiki/index.php/Citadel_-_1988_Cat:_P305_Adventurers) it's called Trader/Merchant "Slymm".
