Lovely - thanks for the piccys.
For what it's worth I would agree with a previous comment made re the wash.
You could turn your well painted army of Kislev and Tomb Kings in gorgeous armies by using a wash like Devlan Mud - or at the risk of being branded a heretic by some on the forums - use a medium strength army dip?
I wouldn't do it with the dwarfs as they appear to ahve aenough contrast already.
A single test pilot unit is always a good way to go though before risking ruining an entire army and then crying!
