Nice FX on the Aardvark bombing run.
I might be able to be give you a hand, but I won't pretend that PFX is my strongest skill - there is very little reference material for the WW1 stuff I usually end up doing, so it's made from my not-so-arty side. Give me good reference, of course, and I can replicate what I see.
www.doc.ic.ac.uk/~swb04/smoke.JPG is a little flamethrowing man I knocked off a while back. And yes, I'm well aware the flame itself goes on for too long; that's been fixed since the shot. :P
http://www.battlefield1918.de/images/?id=4393 is one of general smoke from factories and a train. A PR shot from a while back.
I realise those aren't amazing wow seks jizz shots, and I know how important eye candy is to CWC, so I might not be much help. But the offer is there if you want some of the smaller stuff doing.
